Hi all,
I am having one problem with one project I have just made compile. It's one of the plugins of the windows' multiprotocol IM program, Miranda.
I will try to explain what my problem is. After solving some issues with compilation (mainly some undefined names - functions - in std namespace - it's a C++ project), I tried to run the application and when asking the plugin to connect to one IRC server (it is the application's IRC protocol plugin) it crashes with this error:
Unhandled exception: page fault on read access to 0x00000004 in 32-bit code (0x41d551de).

Which if I understand the dump well is due to a problem in __clone function trying to access 0x00000004 (eax). Am I right?
Then I tried to debug and to get more information. I got this other line in the new dump: wine: Unhandled page fault on read access to 0x00000004 at address 0x41d551de (thread 005d), starting debugger...
And here I am copying the previous lines of the debug information on that thread (005d): 005d:Call ntdll.RtlFreeHeap(40350000,00000000,42cef188) ret=407bdbd0 005d:Ret ntdll.RtlFreeHeap() retval=00000001 ret=407bdbd0 005d:Call ntdll.RtlEnterCriticalSection(40654b04) ret=405c1ee1 005d:Ret ntdll.RtlEnterCriticalSection() retval=00000000 ret=405c1ee1 005d:Call ntdll.RtlLeaveCriticalSection(40654b04) ret=405c1f2e 005d:Ret ntdll.RtlLeaveCriticalSection() retval=00000000 ret=405c1f2e 005d:Call kernel32.ResetEvent(000000d4) ret=405bf4d0 005d:Call ntdll.NtResetEvent(000000d4,00000000) ret=404e45d8 005d:Ret ntdll.NtResetEvent() retval=00000000 ret=404e45d8 005d:Ret kernel32.ResetEvent() retval=00000001 ret=405bf4d0 005d:Call kernel32.WaitForSingleObject(000000cc,ffffffff) ret=405bf4e6 005d:Call ntdll.NtWaitForMultipleObjects(00000001,435108a4,00000000,00000000,00000000) ret=404e3dd1 005d:Ret ntdll.NtWaitForMultipleObjects() retval=00000000 ret=404e3dd1 005d:Ret kernel32.WaitForSingleObject() retval=00000000 ret=405bf4e6 005d:Call kernel32.GetCurrentProcess() ret=405bf4fd 005d:Ret kernel32.GetCurrentProcess() retval=ffffffff ret=405bf4fd 005d:Call kernel32.GetCurrentThread() ret=405bf504 005d:Ret kernel32.GetCurrentThread() retval=fffffffe ret=405bf504 005d:Call kernel32.GetCurrentProcess() ret=405bf50b 005d:Ret kernel32.GetCurrentProcess() retval=ffffffff ret=405bf50b 005d:Call kernel32.DuplicateHandle(ffffffff,fffffffe,ffffffff,43510ab8,00000010,00000000,00000000) ret=405bf522 005d:Call ntdll.NtDuplicateObject(ffffffff,fffffffe,ffffffff,43510ab8,00000010,00000000,00000000) ret=404cda94 005d:Ret ntdll.NtDuplicateObject() retval=00000000 ret=404cda94 005d:Ret kernel32.DuplicateHandle() retval=00000001 ret=405bf522 005d:Call msvcrt.realloc(42d02040,00000050) ret=405bf547 005d:Call ntdll.RtlReAllocateHeap(40350000,00000000,42d02040,00000050) ret=407bdc8f 005d:Ret ntdll.RtlReAllocateHeap() retval=42d02040 ret=407bdc8f 005d:Ret msvcrt.realloc() retval=42d02040 ret=405bf547 005d:Call kernel32.GetCurrentThreadId() ret=405bf58e 005d:Ret kernel32.GetCurrentThreadId() retval=0000005d ret=405bf58e 005d:Call kernel32.ReleaseMutex(000000cc) ret=405bf5b4 005d:Call ntdll.NtReleaseMutant(000000cc,00000000) ret=404e47d3 005d:Ret ntdll.NtReleaseMutant() retval=00000000 ret=404e47d3 005d:Ret kernel32.ReleaseMutex() retval=00000001 ret=405bf5b4 005d:Call kernel32.SetEvent(00000184) ret=41d9b4a7 005d:Call ntdll.NtSetEvent(00000184,00000000) ret=404e4488 005d:Ret ntdll.NtSetEvent() retval=00000000 ret=404e4488 005d:Ret kernel32.SetEvent() retval=00000001 ret=41d9b4a7 005d:Call ntdll.RtlEnterCriticalSection(41dc78f8) ret=41d55164 005d:Ret ntdll.RtlEnterCriticalSection() retval=00000000 ret=41d55164 005d:Call kernel32.lstrlenA(7c0f9d2a "") ret=41d55193 005d:Ret kernel32.lstrlenA() retval=00000000 ret=41d55193 005d:Call ntdll.RtlEnterCriticalSection(41164de8) ret=4111a00c 005d:Ret ntdll.RtlEnterCriticalSection() retval=00000000 ret=4111a00c 005d:Call ntdll.RtlLeaveCriticalSection(41164de8) ret=4111a044 005d:Ret ntdll.RtlLeaveCriticalSection() retval=00000000 ret=4111a044 005d:Call ntdll.NtCreateEvent(43510648,001f0003,43510608,00000001,00000000) ret=4049fb55 005d:Ret ntdll.NtCreateEvent() retval=00000000 ret=4049fb55
All this is absolutely cryptic to me. Does anyone ge something from this information? Is there any way to get to know where the aplication is crashing?
Thank you. Sergio.
