Bug-Reported-by: Andreas Schwab <schwab@suse.de>
Bug-Reference-ID: <20051213141916.4014A394BFABD@sykes.suse.de>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2005-12/msg00038.html

Bug-Description:

A problem with the readline callback interface can result in segmentation
faults when using the delete-char function via a multiple-key sequence.
Two consecutive calls to delete-char will crash the application calling
readline.

Patch:
