It sounds like a bug.  However, gdb-4.18 is rather old.  Have you
tried either gdb-5.0 or the current development version?

For information on how to fetch a development version, see: 

    http://sources.redhat.com/gdb/#download

If you still see the bug when using a debugger built from the current
development sources, I'd appreciate it if you'd send us a test case.
