This is presumably a bug in that Red Hat-supplied version of GDB. We
can't help you with it on this list; if you can reproduce it with the
version of GDB in CVS, please let us know, otherwise you should discuss
it with Red Hat.
Code was added sometime last year to handle loading the vDSO on attach.
