vld2.5.1 Application start up failed because of access violation VS2015 Update3

[Xuxiaotianonlyone]

Hello, could anyone help me?

There is a rare problem troubled me. I'm checking memory leak of my vs2015 solution with vld2.5.1. I have tried to check one simple vs2015 project,and the vld works well.But when I use vld to check our project that include about 100 subprojects, the generated application started up failed. (the application need to load some dlls) .

The phenomenon is a break dialog pop out and the info is a access vilolation exception: 0x0000000003241099 (vld_x64.dll) 0xC0000005: read location 0x00000000001C9D4A

This is the callstack info:

vld_x64.dll!FindRealCode(void pCode) 行 433 C++ vld_x64.dll!PatchImport(HINSTANCE__ importmodule, moduleentry_t patchModule) 行 551 C++ vld_x64.dll!PatchModule(HINSTANCE__ importmodule, moduleentry_t patchtable, unsigned int tablesize) 行 668 C++ vld_x64.dll!VisualLeakDetector::attachToLoadedModules(Set newmodules) 行 904 C++ vld_x64.dll!VisualLeakDetector::RefreshModules() 行 2332 C++ vld_x64.dll!LdrpCallInitRoutine(void BaseAddress, unsigned long Reason, void Context, unsigned char()(void , unsigned long, _CONTEXT *) EntryPoint) 行 98 C++

So,I tried to debug vld's source code to find the reason.And I found that in the utility.cpp in PatchImport function (line 489) ,when "importmodule == MagiQpdSrv_x64_nc_fw40_15001.dll " , program break off in LPVOID func = FindRealCode((LPVOID)thunk->u1.Function);(line 551).
At the same time, Function Parameter "(LPVOID)thunk->u1.Function" is a wild pointer. So program break off in function FindRealCode.

Does anyone know the solution for my problem?Thanks very much and look forward to a reply!

Hi Xuxiaotianonlyone, Hi everybody !

We are experiencing a similar issue. We have a project which loads several plugin dlls. When VLD is activated loading the DLLs causes the same exception in LoadLibrary() as described above. ( 0xC0000005 - access vilolation exception). We are using VS2015 with VLD 2.5.1 and are building in 32 Bit. The issue in Windows 7 64 Bit. My colleague using Windows 7 32 Bit has no problems.

vld_x86.dll!FindRealCode(void pCode) Line 433 C++ vld_x86.dll!PatchModule(HINSTANCE__ importmodule, moduleentry_t ) Line 666 C++ vld_x86.dll!VisualLeakDetector::attachToLoadedModules(Set newmodules) Line 902 C++ vld_x86.dll!VisualLeakDetector::RefreshModules() Line 2332 C++ vld_x86.dll!LdrpCallInitRoutine(void BaseAddress, unsigned long Reason, void Context, unsigned char(__stdcall)(void , unsigned long, _CONTEXT *) EntryPoint) Line 95 C++

Hello all. My team recently had this problem with NUnit in 64-bit.

Not sure if this applies to the original issue, but for us the solution was to use VS Test (https://github.com/Microsoft/vstest) (from https://www.nuget.org/packages/Microsoft.TestPlatform.Portable/) with the NUnit adapter from NUnit, to run the NUnit tests, which VLD seems to have no issue attaching to, and FindRealCode has no issue.

The same problem, finally, I solve it by change the operating system encoding: don't use Unicode.
