           Summary: System.Diagnostics.Process SIGSEGV
    Classification: Mono
           Product: Mono: Runtime
           Version: 2.10.x
          Platform: x86
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: generics

           Blocker: ---


Application calling native executable started SEGV'ing with the 2.10.x build. 
Works fine with 2.8 (OSX and Linux) and .NET (with OS specific compiled native
executable -- ffmpeg in this case).  Have downgraded to 2.8 and all is fine
again.

Previous version had:
_wapi_handle_unref: Attempting to unref unused handle 0x24a941

errors, but not sure if that is related.
