            Bug ID: 45289
           Summary: Wine Crashes Some Programs If Compiled with AVX
                    Support
           Product: Wine
           Version: 3.9
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: ben at xnode.org
      Distribution: ---

This is a really specific bug and I'm not sure what other programs/games it
affects. I assume there are more, but this is the only example that I've
reliably run into at the moment:


== To Recreate
Run Cemu under a 64bit Prefix. Start Mario Kart 8. After Mario announces the
game, it will crash.


== Workaround
Compiling Wine without AVX support (i.e. adding the -mno-avx C/XXFLAG) negates
the issue.


People won't see this when using distro packages because they'll be compiled
using something like -march=x86-64 which doesn't enable any of the AVX options
(as they aren't available in all processors). If you compile it yourself using
something like -march=native then GCC will enable the AVX functions which in
turn triggers this issue.


I saw this behaviour on both my old i7-5775C and the i7-8700K which has since
replaced it.

In case it's relevant, it looks like this problem may have not existed before
Wine 3.0 because I've tracked down an old post of my own wherein I stated
(regarding the Mario Kart 8 crash on Cemu):

=======================
Tried on a brand new Wine 3.2 prefix, same issue (Segmentation fault after the
splash screen). Works fine with Staging 2.21.

More specifically:
002c:fixme:seh:RtlCaptureStackBackTrace (0, 40, 0x25152ba0, (nil)) stub!
002c:err:seh:call_stack_handlers invalid frame 25153728 (0x116a0000-0x117a0000)
002c:err:seh:NtRaiseException Exception frame is not in stack limits => unable
to dispatch exception

EDIT: The issue was vcrun2015. Wine-staging didn't need it. Standard wine does,
for some reason.
=======================

Not sure if the vcrun2015 issue was a red-herring as that's installed now but
no-longer fixes the issue.
