Bug ID: 51396
           Summary: cl.exe sometimes fails with internal compiler error
           Product: Wine
           Version: 6.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Cl.exe from MSVC 2019 Build Tools sometimes fails with: "fatal error C1001:
Internal compiler error." A workaround is setting vcruntime140_1 to native.

This is possibly caused by unsupported flag in __CxxFrameHandler4:
0b24:fixme:seh:__CxxFrameHandler4 unsupported flags: 7a

which is unsupported FUNC_DESCR_IS_SEPARATED in
dlls/vcruntime140_1/except_x86_64.c

Not critical since the workaround exists. I'm ready to test this when the flag
is implemented.
