Bug ID: 55755
           Summary: ntdll:wow64 - The 32-bit test_modules() fails to find
                    the main module in Wine's new WoW mode
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll

ntdll:wow64 - The 32-bit test_modules() fails to find the main module in Wine's
new WoW mode:
wow64.c:1568: Test failed: main module not found
See https://test.winehq.org/data/patterns.html#ntdll:wow64
In particular one can see this issue on fg-deb64-i386, fgtb-debian11-i386,
fgtb-debian12-i386 and rbernon-*-wow64 which all run the 32-bit tests in the
new Windows-on-Windows Wine mode. This failure does no happen in the 64-bit
test, or when running in a pure 32-bit environment or in the old
Windows-on-Windows mode.
This also happens on macOS when running the 32-bit tests in the new WoW mode
(see mac_rbernon-macos-*-wow64).
A bisect shows that this failure started with the commit below:
commit de81e2ea41b27a14f88177639c5b5d35a210b5bd

ntdll: Only create the main module on the 32-bit side for wow64.
This means this most likely has the same fix as bug 55744.
