Yes.  There are 2 workarounds.  One is to use a /usr/libexec/elf/gdb
from -stable (or -current pre-binutils).

The other is to rebuild gdb with a patch that breaks buildworld. Patch
below.

The problem is that xmalloc() and xrealloc() are multiply defined and
the rtld keeps looking them up in shared libs, getting confused, and
looking them up again, etc.
