Bug ID: 55102
           Summary: Rework __TRY / __EXCEPT to work on other architectures
                    than x86, e.g. x86_64
           Product: Wine
           Version: 8.10
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

There is wine/exception.h that provides a try/catch mechanism using the macros
__TRY / __EXCEPT.

There's two versions
1) Use compiler exceptions (define USE_COMPILER_EXCEPTIONS), needs compiler
support
2) Use the wine version of exception handling

GCC doesn't support those compiler exceptions, so that's not really an option.
The wine implementation however doesn't work on windows.

Underlying problem is that the wine try/catch sets up exceptions like x86, this
assumption fails when using x86_64.
x86 uses a stack of frame pointers in the TEB, while x86_64 (and others) use
SEH metadata instead.

Since it would be nice using try/catch in tests, this would be a welcome
improvement.
