  • Bug fix for crash during shutdown of the target application. This crash was caused by a change to how the operating system behaves, causing an endless loop of recursing calls (about every 10th call would cause the recursion). This bug definitely affects Windows 11, and possibly affects Windows 10.
  • Bug fixes for three crashes during shutdown (inside ExitProcess()) involving dbgHelp internals or CRT internals being incorrect.

    • Speed up for virtual tree control deleting rows.
    • Extra error reporting relating to symbol tracking on diagnostic tab.
    • Internal minor bug fixes.
    • Bug fix for "automatically add to PDB search path". Paths are reset to match the file settings dialog/wizard prior to launching/injecting/waiting on an application. Paths are then rediscovered. This means that for situations where you have multiple versions of the same DLL in your development environment, the correct paths to your PDBs are used, rather than paths to PDBs in potentially other directories on your system than the particular DLL in use at the time.
    • Bug fix for SAFEARRAYs of BSTRs, these were not correctly accounted for when the SAFEARRAY was passed to ::VariantClear(). This resulted in BSTRs incorrectly being marked as leaked when they were not leaked. Typically this manifests when using COleSafeArray to hold BSTRs.
    • New hook for SafeArrayGetElement(), so that BSTRs returned from a SAFEARRAY are tracked.
    • Default for hooking delay loaded functions is now TRUE.
    • Default for hooking delay loaded DLLs is now TRUE.

    Version 2.59
    Version 2.59 includes the following new functionality:

    • Addition of various CRT hooks for the global namespace. In MFC applications these functions would not normally be called, as the MFC equivalent would be called. For applications not using MFC, memory allocated via these functions would not be tracked. Version 2.59 fixes this.
      • Visual C++ 4.2: global namespace ::operator new(unsigned int size, int blockType, char const *filename, int line); (debug only)

    • Improved robustness for the function hooking code that alters machine code to insert hooks. This results in better reliability for the uninitialised data detection code and for the code that tracks COM object reference counts.
    • Performance increase for unhooking uninitialised data hooks when a DLL is unloaded. Performance is now Order N rather than Order N2.
    • Addition of a simple tutorial on the help menu. The tutorial will be improved in future releases.
    • Addition of this file on the help menu.
    • Novice user interface settings are retained between each time the novice wizard is displayed. Previously the wizard always reset the settings, which confused some people.
    • When you switch to the Novice user interface, you are asked to configure the settings to work with.
    • Leak detect and garbage collect buttons have been removed because they were causing too much confusion - leaks detected more accurately and faster by running the program to completion rather than trying to detect the leaks in situ.
    • Addition of a raw stack walk, to aid in stack walking when no frame pointer information is available. Please note that when this is enabled stack traces may have unusual entries in them.

    Version 2.24
    Version 2.24 includes the following new functionality:

    • Minor maintenance improvements.
    • Bug fix for discard stack traces for freed data.

    • New logic for handling uninitialised data detect when first object found is on the stack or is statically allocated.
    • Uninitialised data detect now includes memory allocated using HeapAlloc().
    • New example code demonstrating overloading of new and delete operators so that class objects can be allocated on a HeapAlloc() heap. This example demonstrates tracking of allocations/deallocations of these objects and the detection of uninitialised data in these classes.

    Version 2.22
    Version 2.22 includes the following new functionality:

    • Bug fix for crash in stub whilst PDB walking. This bug only affected uninitialised data detection for some applications.

    Version 2.16
    Version 2.16 includes the following new functionality:

    • Improved symbol, datatype and coverage handling for the case when a DLL is unloaded and another DLL is loaded into the same address space. Previously, the symbol cache addresses would resolve to the addresses supplied for the first DLL. The correct symbols are now resolved.

    Version 2.15
    Version 2.15 includes the following new functionality:

    • Search for data bug fix.
    • User interface mode bug fix.
    • Tree expand not adjusting scrollbar bug fix.

    • Bug fix when shutting down the stub.

    Version 2.13
    Version 2.13 includes the following new functionality:

    • Dependent DLLs that are loaded as a dependency of another DLL are hooked. The dependent DLLs do not get loaded via a call to LoadLibrary() and were not being hooked. This is now fixed.
    • The Objects view has been reworked. The new implementation displays more statistics including type, size, number of allocations, maximum number of allocations, cumulative number of allocations, cumulative size percentage, cumulative object count percentage.
    • The search path used to find PDB files is now automatically updated as DLLs are found.

    Version 2.12
    Version 2.12 includes the following new functionality:

    • Support for NT Services. Memory Validator can now detect memory leaks, etc. in NT Services.
    • Sample NT Service showing how to use Memory Validator with NT Services.
    • Sample client for the NT Service.
    • Sample utility to control if Memory Validator is loaded by the Sample NT Service.
    • Bug fix for CreateProcess() startup method. Some applications would get a single step exception using this method because of incorrect calls to VirtualProtect(). This has been fixed.
    • A very rare bug that may occur after a tested application has shutdown has been fixed. Memory Validator has a high speed memory allocator that is used for managing interprocess communications work packages. If an allocation request for more than 128KB is made under specific conditions a crash may occur when using the memory allocated. This has been fixed.
    • The launch wizard for Novice and Intermediate modes sometimes would not enable the Next >> button. This has been fixed.

    Version 2.11
    Version 2.11 includes the following new functionality:

    • Add support for PDB files in any directory.
    • Bug fix for a very rare crash during program shutdown after MSVCRT.DLL has unloaded. Most customers will not have seen this bug.

    • Bug fix for background memory scan. When a corrupted memory block is found it is now correctly displayed when automatic display of errors is selected.

    Version 2.10
    Version 2.10 includes the following new functionality:

    • New launch mode, CreateProcess that is more robust and starts all programs by modifying the program's startup code. This new mode does not fail on the 1% of programs that did fail with the previous Suspend mode.
    • New user interface modes. User can now choose between Novice, Intermediate and Expert modes.
    • New user interface wizards for setting options and launching applications.
    • Fixed crash caused by race condition. This was a very rare bug.

    Version 2.08 includes the following fixes:

    • Graphical dialogs on the Objects tab now function correctly.

    Version 2.06
    Version 2.07 includes the following fixes:

    • Memory Validator held onto the process handle of the process being monitored after the process had finished executing. This prevented the process from being rebuilt without closing Memory Validator. This has been fixed.
    • Miscellaneous bug fixes.

    Version 2.06
    Version 2.06 includes the following fixes:

    • Speed improvements to stub and user interface data processing.
    • Both stub and user interface require less memory to store the collected data.
    • Crash whan "Analyze" on Coverage window clicked fixed.
    • Crash when session deleted (explicit deletion, session purging or Memory Validator shutdown) fixed.
    • Miscellaneous crashes related to the same problem listed above also fixed.
    • Improved example program to show code highlights prior to executing the sample code.
    • Cross Thread dialog has been given a significant speed improvement. This dialog also requires less memory as a result.

    • All query dialogs that can display large volumes of data have been given a significant speed improvement. These dialogs also require less memory as a result.
    • Miscellaneous bug fixes and speed improvements.
    • LoadIcon, LoadCursor, LoadCursorFromFile are no longer tracked as these handles are shared and cannot be deleted. This removes spurious trace data from the data log.
    • Different default settings to display different data sets when a session is running and when a session has completed.
    • Miscellaneous resizing bug fixes.
    • Improved Session Export dialog.
