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:

Which if I understand the dump well is due to a problem in __clone function trying to access 0x00000004 (eax). Am I right?
Nope you looking at the wrong end. The address at fault is 0x41d551de which is frame 1. Also it looks like you have stripped wine libs. That's why you don't see function names nor their parameters.
005d:Call ntdll.RtlLeaveCriticalSection(41164de8) ret=4111a044
thread ID function name called arguments return address
005d:Ret ntdll.RtlLeaveCriticalSection() retval=00000000 ret=4111a044
thread ID function name returning from return value return address
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?
What you might need is a WINEDEBUG=+relay,+seh debug channels. That should point you at the place where exception occurred.
PS You might want to look at developer's guide on winehq.org.
