--- Comment #17 from Paul Gofman pgofman@codeweavers.com --- Created attachment 68889 --> https://bugs.winehq.org/attachment.cgi?id=68889 test patch
(In reply to Juozas from comment #16)
Found the commit that caused crash, titled "ntdll: Support AVX registers for other thread in Nt{Get|Set}ContextThread()." with hash 419abd49a1f816e5a869dbf4cc81114cd516138b All versions after the commit including itself causes a crash for me. Might be cpu issue as I'm running on a quite old cpu (Intel Pentium Dual-Core E6300 @ 2.80GHz)
Thanks for bisecting. Also, knowing that this is a quite old CPU might be helpful.
The attached patch checks one guess I have and also adds a bit of extra output.
Could you please try it with the attached patch (on top of current Wine), does it change anything?
In any case, could you please attach WINEDEBUG=+pid,+seh,+timestamp log with this patch? And if it is still crashes with the patch, also attach 'ntdll.so' 32 bit binary from Wine installation which is used to make this log (this way I should be able to see where it is faulting exactly).
