Bug ID: 47736
           Summary: __ASM_CFI not working on mac
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Mac OS X
            Status: NEW
          Keywords: regression
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
   Regression SHA1: f2503a3e0d10bb563bc7ab62c6ff5093e6ad3f15

The problem is reproducible in 64-bit wine build on Mac (built with clang).

The simplest way of reproducing the problem is to write application with
following code:
try {
    RaiseException(0, 1, 0, NULL);
} catch(...) {
}
It will crash when relay debug channel is enabled. It's caused by wine not
being able to unwind relay_call function.
