Just to give everyone an update, the glibc problem is fixed by not calling
the malloc atfork hooks when glibc's malloc is not used (bash ships its own
malloc implementation).  The following change, which is not yet in glibc,
fixes that (you can find the actual patch on libc-alpha@sources.redhat.com).

2002-11-18  Wolfram Gloger  <wg@malloc.de>

        * malloc/arena.c
        (ptmalloc_lock_all, ptmalloc_unlock_all, ptmalloc_unlock_all2): Do
        nothing if not initialized.  Bug report from Marcus Brinkmann

I just made debs from the official 2.3 release with this patch, and it
appears to be working fine.
