I think you may be seeing a linker bug.  Newer versions of gdb have
a fix to work around the bug, but gdb-5.0 did not.

For more information, see the threads associated with:

    http://sources.redhat.com/ml/gdb/2001-08/msg00221.html
    http://sources.redhat.com/ml/gdb-patches/2001-09/msg00003.html

The simple fix is to update to a newer version of gdb.  Either 5.2
or the current development sources should be fine.
