            Bug ID: 51182
           Summary: test_write_console() fails in conhost:tty on Windows
                    1909
           Product: Wine
           Version: 6.8
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org
          Reporter: fgouget(a)codeweavers.com

test_write_console() fails in conhost:tty on Windows 1909, probably because
conhost.exe is broken in Windows 10 <= 2004:

These failures can be reproduced on cw-rx46-1909, wc-gtx560-1909 and the
TestBot's w1064v1909:

https://test.winehq.org/data/patterns.html#conhost.exe:tty

They don't happen on Windows 10 1809 and lower because the test detects that
conhost.exe is broken there:

tty.c:1645: Tests skipped: Skipping tty output tests on broken Windows version

And the test succeeds on Windows 10 >= 2004 (or rather has unrelated failures).
So it looks like 1909 fell between the cracks and that the test should skip too
somehow.

This test was introduced by the commit below:

--- Comment #1 from François Gouget <fgouget(a)codeweavers.com> ---
Nowadays the failures mostly take the form of a timeout on 1909. However
running the test manually can also result in it crashing with a NULL pointer
dereference.
