orbit-idl seg fault on simple .idl

["Sheena Golish" <res0a5dd verizon net>]

My difficulty is that orbit-idl 0.5 seg faults and dumps core on the
following simple .idl file (this is a MODIFIED version of an OMG DTF file).
Sun's idlj compiler seems to like it just fine.  If I comment out the two
interfaces orbit-idl works fine.  If I comment out the second of the two
interfaces, orbit-idl produces output, but crashes after.

This must be a simple problem, since orbit-idl does the same thing on
STANDARD OMG published files.  Please help.

Thanks,
Ray
