--- Comment #11 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- When comparing the +relay logs between patched and unpatched Wine it is clear to me that the crash occurs at the point where SetFileCompletionNotificationModes should be called, and that stubbing the function avoids that crash. I believe that the program does not check for the return value of GetProcAddress and jump to address 0x0, that would explain why the backtrace is
--- snip --- Backtrace: =>0 0x0000000000000000 (0x0000000000000000) 0x0000000000000000: -- no code accessible -- --- snip ---
The +relay log didn't tell me anything more, even with +winsock. I made a +all,-heap log and saw nothing more either.
I attach full debug output split between the three involved threads. Thread 0028 is the one that crash without the patch. Threads 0051 and 0038 are the ones that crash with the patch, in that order.
I also attach full debug output of thread 0028 without patch applied, for comparison.
