            Bug ID: 52213
           Summary: Tests for mfreadwrite crash after pthread_exit
           Product: Wine
           Version: 7.0-rc1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

   Regression SHA1: 4ba31162c37ea237763e650f6242535d86ffb170
      Distribution: Debian

Since commit 4ba31162c37ea237763e650f6242535d86ffb170 test for mfreadwrite
crash in a funny way on my system: one of the threads of the tests crashes
after calling pthread_exit, which is, as far as I understand, the last place in
which we have the control of a dying thread.

The system on which I am trying this is a rather recently installed Debian
unstable amd64, for which I did not do any specific tinkering, say, of the
dynamic loader, glibc or anything else. So I can't think of anything unusual
that could trigger this on my system. However, my first impression is that
somehow we corrupt something in the pthread or glibc status so that the
teardown goes badly.
