Application was unable to start correctly #2

The errors above were with the prebuilt release, so I tried to build BugInsight and got an error following steps from https://github.com/JochenBaier/BugInsight/blob/main/Build_from_source.md $ cmake --build . --config Release --parallel |

Thank you for reporting this. Please delete build folder and repeat the cmake steps to see if you got cmake errors. |

Hello, I'm getting these compiler errors for Debug and Release:
It built the executable, but then I get this error when trying to run, and I cannot find the DLL mentioned. I used the VS2022 Command Prompt.
Here is the build log before the compiler errors:
|
at mutex_monitor.hpp: using _Thrd_result = int; // add this
using _Mtx_lock_t=_Thrd_result(__cdecl*)(_Mtx_t) noexcept;can fix compile error |
it crash at first below code: // buginsight_dll\stacktrace\stacktrace.cc
TM_ATTRIBUTE_NOINLINE int GetStackFrames(void** result, unsigned long* p_hash, int p_max_depth, int p_skip_count, bool p_check)
{
// it can not use a static object, because it do not init all global and static variable.
static RtlCaptureStackBackTrace_Function* const RtlCaptureStackBackTrace_fn=(RtlCaptureStackBackTrace_Function*)GetProcAddress(GetModuleHandleA("ntdll.dll"), "RtlCaptureStackBackTrace");
...
}change as static RtlCaptureStackBackTrace_Function* RtlCaptureStackBackTrace_fn = nullptr;
TM_ATTRIBUTE_NOINLINE int GetStackFrames(void** result, unsigned long* p_hash, int p_max_depth, int p_skip_count, bool p_check)
{
if (RtlCaptureStackBackTrace_fn==nullptr) {
RtlCaptureStackBackTrace_fn = (RtlCaptureStackBackTrace_Function*)GetProcAddress(GetModuleHandleA("ntdll.dll"), "RtlCaptureStackBackTrace");
}
...
}
then it crash at second below code: //buginsight_dll\helper\dbghelp_api.cpp
DWORD bi_symsetoptions(DWORD SymOptions)
{
std::lock_guard lock(g_mutex); // ---> the g_mutex is not init, when use it will crash.
//assert(SymSetOptions_fptr);
//return SymSetOptions_fptr(SymOptions);
return SymSetOptions(SymOptions);
}this is because //buginsight_dll\dll_main.cpp
loader_t g_loader; ------> it's constructor will call InitializeSymbolizer->dbghelp_api::bi_symsetoptions->std::lock_guard lock(g_mutex);
// but sometime g_mutex is init later than g_loader.

i will take look this weekend. |
thanks. // dll_main.cpp
loader_t* g_loader=nullptr;
__declspec(noinline)
BOOL WINAPI DllEntryPoint(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpReserved)
{
...
if(fdwReason == DLL_PROCESS_ATTACH || fdwReason == DLL_THREAD_ATTACH)
{
if(!_CRT_INIT(hinstDLL, fdwReason, lpReserved))
{
return(FALSE);
}
if (g_loader==nullptr) {
g_loader = new loader_t();
}
}
if(fdwReason == DLL_PROCESS_DETACH || fdwReason == DLL_THREAD_DETACH)
{
delete g_loader;
g_loader = nullptr;
if(!_CRT_INIT(hinstDLL, fdwReason, lpReserved))
{
return(FALSE);
}
...
}but it can not monitor global variable's memory alloc and free. |
F12 on _Thrd_result goes with Community to C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.40.33807\include\xthreads.h
buginsight_dll\dll_main.cpp: buginsight_dll\helper\dbghelp_api.cpp: with this fix the order should be defined since g_mutex and g_loader are in the same translation unit |
I am use "Microsoft Visual Studio Professional 2019 Version 16.11.22, Plaform Toolset v142"
it is fixed by your solution. Thanks. |
I tried to use BugInsight on two Qt applications and they both failed to work.
An error dialog showed the message:
"The application was unable to start correctly (0x0000142). Click OK to close the application."
The command line showed this:
[BugInsight] [info] BugInsight Application under test: 'MyApp.exe'
[BugInsight] [info] Loading 'BugInsight' into application under test.
[BugInsight] [warning] Call PeekNamedPipe() failed: 'The pipe has been ended.'.
[BugInsight] [info] Application under test finished with exit code '-1073741502'
I'm using Qt 6.2.12 and MSVC 2022.
