Hi Pavel, Can you run your app under winedbg? When I run my app under winedbg, it segfaults inside the application code with a bad read access. The specific instruction it faults on is movl 0x10(%esi),%eax (aka mov [esi+0x10],eax for IDA users). I'm curious to know if your app uses the same library as mine... --Rob

...seh:EXC_CallHandler handler returned 1 0806d398:warn:resource:RES_FindResource page fault This time eip is in pe_resource.c in libntdll.so, the find_entry_by_id method. The exception is handled by NTDLL.DLL.__wine_exception_handler in libntdll.so. Finally, about 2000 lines later, our friend the LoadOEMResource exception occurs. So we have three exceptions in a row. The first is apparently intercepted by the application. The second is generated by trying to display the message box popped up by the first exception. The third is generated in LoadOEMResource, *probably* long after the application was...

More information on exception #2. The offending function is: /********************************************************************** * find_entry_by_id * * Find an entry by id in a resource directory */ static const IMAGE_RESOURCE_DIRECTORY *find_entry_by_id( const IMAGE_RESOURCE_DIRECTORY *dir, WORD id, const void *root ) {

Hmm. I'm just throwing this out there. Maybe the problem will always happen when the application wants to catch an exception but wine catches it instead, and then some internal data structures get trashed when the app resumes? --Rob

Oh, I think I see now. There was a call to VIRTUAL_SetProt, which protected memory mapped regions of memory, before the first exception: 0806d398:trace:virtual:VIRTUAL_SetProt 0x459000-0x459fff c-r-- View: 0x400000 - 0x765fff 28 0x400000 - 0x400fff c-r-- 0x401000 - 0x458fff c---- 0x459000 - 0x459fff c-r-- 0x45a000 - 0x758fff c---- 0x759000 - 0x765fff c-rw- And

Interesting. In my app, the first exception appears to occur because the app tries to read memory at 0x456010 from a segment that had been declared c---- by a previous call to VIRTUAL_VirtProt. Pavel, I'm willing to bet your error is the same. So what gives? --Rob

Hooray, I got gdb to do what I need, to skip the first exception and break before the second. The key commands are: gdb (winepath)/bin/wine Set the arguments: > set args --winver nt40 yourapp Tell gdb to pass segmentation faults to the program: > handle SIGSEGV nostop pass Set a breakpoint at main: > b main Run the program: > run This loads all the shared libraries, and
