Bug ID: 51500
           Summary: ntdll:exception test_wow64_context() randomly fails on
                    Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]

test_wow64_context() regularly gets one of the following two failures on
Windows:

exception.c:4370: Test failed: cs32: ecx f6a10000 / 4EAECB33F6A10000
or
exception.c:4450: Test failed: cs64: rsp not inside 64-bit stack
0000000002B7F388 / 00000000009E0000-0000000000A1FD20

It looks like at most one failure happens in a given run. They happen on
Windows 8.1 to Windows 10 2009, only QEmu VMs so far.
But the failures only happen about 6.9% of the time so the above data is not
100% certain yet.

The tests were added in this commit:

commit 9ae2b046ef2f645b122a2554cc8e32d3a3d79ccc

As may be evident from the commit, these only impact the 64-bit WineTest.
