Description:
[Detailed description of the problem, suggestion, or complaint.]
when i press the 0/ins key on my numeric keypad, if numlock is off bash
exits with SIGSEGV. to demonstrate this, i recompiled bash like this:
CFLAGS="-g" ./configure --with-curses
heres the output of gdb....
~/temp/bash-2.05b$ gdb ./bash

heres the output of showkey...
# showkey
kb mode was RAW
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]
press any key (program terminates 10s after last keypress)...
keycode 28 release <--- released the enter key
keycode 82 press <--- pressed the 0/ins key ( numlock off)
keycode 82 release <--- released the 0/ins key ( numlock off)
this worked with the previous version of readline (4.2a), ive just
tested it.

to occur.]
start bash, use showkey to confirm that your 0/ins key has keycode 82
press the 0/ins key. bash exits with SIGSEGV.
