BTW, you might want to read this thread: http://sources.redhat.com/ml/gdb-patches/2004-05/msg00594.html For the export stubs bit, the final message from Dan is here: http://sources.redhat.com/ml/gdb-patches/2004-05/msg00741.html I think this "problem" still exists even if you add the strcmp back in. Suggestions on how to deal with this is welcome. randolph -- Randolph Chung Debian GNU/Linux Developer, hppa/ia64 ports http://www.tausq.org/
