--- Comment #5 from Dan Kegel dank@kegel.com 2013-07-23 11:48:18 CDT --- Without WINEDEBUG=warn+heap, I see a crash (usually a heap corruption crash) with StringTableDestroy in the stack trace in 28 out of 150 runs (and some other crash in 9 out of the 150 runs).
With WINEDEBUG=warn+heap, I see only two crashes out of 54 runs, both in SetupFindFirstLineW.
I opened bug 34120 for the heap corruption before your reply. Looking forward to your patch.
