            Bug ID: 55756
           Summary: The 32-bit ntdll:wow64 crashes in the new WoW mode on
                    macOS
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs(a)winehq.org
          Reporter: fgouget(a)codeweavers.com

The 32-bit ntdll:wow64 crashes in the new WoW mode on macOS:

[... skip failures from bug 55752, bug 55754 and bug 55755...]
wow64.c:1773: got init block 000000f0
Unhandled exception: page fault on read access to 0xffffffff in segmented
32-bit code (0107:00dd000e).
Assertion failed: curr_mode == stm_32bit, file ../wine/dlls/dbghelp/cpu_i386.c,
line 278
ntdll:wow64:0e24 done (-1073740972) in 2s 665B

See https://test.winehq.org/data/patterns.html#ntdll:wow64

The failures are systematic but only happen when running the 32-bit test in a
Windows-on-Windows wineprefix on macOS.

Looking at the pattern one may also think they started on 2023-10-02 but in
fact that's just because before that date the WineTest report had so many other
errors that test.winehq.org rejected the report. In fact the test was already
failing all the way back to at least 2023-09-07 (there is no earlier data).
