Bug ID: 54712
           Summary: ntdll:rtl times out on Windows 10 1607
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]

ntdll:rtl times out on Windows 10 1607:

[...]
rtl.c:2790: Running test 23 (compressed_size=5, uncompressed_size=0,
status=0xc0000242)
ntdll:rtl:00a4 done (258) in 120s 2231B

See https://test.winehq.org/data/patterns.html#ntdll:rtl

The timeouts started on 2022-09-06 and have been systematic since. However when
run on its own the test does not time out and usually runs in under 1s.

The timeout always happens after the "test 23" trace which is also the last
test of test_RtlDecompressBuffer(). Given that the test usually runs pretty
fast it is probable that one of the tests that follows causes a freeze on
Windows 10 1607.

--- Comment #1 from François Gouget  ---
ntdll:rtl may actually crash instead of timing out depending on some unknown
factors:

rtl.c:2668: Running test 23 (compressed_size=5, uncompressed_size=0,
status=0xc0000242)
rtl.c:3492: this is the last test seen before the exception
03ac:rtl: unhandled exception c0000005 at 77765AE5

The crash happens in this test_RtlDestroyHeap() call:

ret = RtlDestroyHeap( heap );

Furthermore the crashes started with the commit below:

Note that the 64-bit test stopped timing out on 2023-07-10 which corresponds to
the GitLab CI's switch to Debian 12 (the TestBot uses the official GitLab CI
winetest.exe binaries).
But the 32-bit test still times out :-(
