           Summary: Defining a COM interop that returns a System.Guid
                    Asserts on JIT compilation for a native->managed call.
    Classification: Mono
           Product: Mono: Runtime
           Version: SVN
          Platform: x86
        OS/Version: Ubuntu
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: interop

Test interop definition thats a Guid

// Returning a Guid doesn't work:
System.Guid get_MakeObjFromText([MarshalAs(UnmanagedType.BStr)] string
bstrText, [MarshalAs(UnmanagedType.Interface)] object _selDst, out int _odt);

// However having it as an out param does work
void get_MakeObjFromText([MarshalAs(UnmanagedType.BStr)] string bstrText,
[MarshalAs(UnmanagedType.Interface)] object _selDst, out int _odt, out Guid g);

Attaching Sample code showing issue.

Assert happens:
 0x08170262 in mono_method_get_wrapper_data (method=0x884c18c, id=6)
    at loader.c:1924

id is 6 but array only has 4 items in it.

Reproducible: Always

Actual Results:

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
