If you run with -ORBtraceExceptions 1 you'll get a message telling which
line in the stub header file has thrown the exception. Looking at that
code will tell you which enum it is that's been sent with an invalid
value, but not which structure it's in.

To work that out, the easiest thing is to modify the generated code that
throws the MARSHAL exception so that it calls abort(). That way your
program will fail at the time the invalid value occurs, and you'll be
able to figure out which structure it's in from the call stack.

Cheers,

Duncan.
