            Bug ID: 49095
           Summary: "stack overflow" when running StarCraft 2
           Product: Wine
           Version: 5.7
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org
          Reporter: bat.misc(a)batbytes.com

wine stdout/stderr

Environment:

- Arch Linux fully updated as of the date of this report.
- Wine master branch (d1f858e03da732c621504f90e349d5170ca3336e) using Arch
Linux wine-staging package configurations. Built with debugging and not
stripped.

When running StarCraft 2 at no particular point during the game, I see this
failure:

0474:err:seh:setup_exception_record stack overflow 340 bytes in thread 0474 eip
deb0986a esp 0f7011dc stack 0xf700000-0xf701000-0xff00000

The overflow is always 340 bytes. When I was trying to diagnose this with
strace, I saw that the thread is doing a lot of network recvmsg/sendmsg
traffic.

The log is attached.

I don't think this bug is related to my other bug #49094.

This appears to be a new regression. I was previously using Arch Linux's
wine-staging package with wine staging version 5.5. That version did not have
this problem.
