Patch Level: 0
Release Status: release

Description:

While working in an interactive shell, I accidentally hit a local umlaut
key. Later, when browsing back in history with the UP key, when
reaching the line with that umlaut, bash terminates after having turned
off console echoing.

hexdump of .bash_history (at the position of the offending history
line):

00001f10  62 69 6e 2f 72 69 6f 0a  63 68 67 72 70 20 75 fc
|bin/rio.chgrp u.|
00001f20  73 20 2f 75 73 72 2f 62  69 6e 2f 72 69 6f 0a 63  
|s /usr/bin/rio.c|


Repeat-By:

Type an 'ü' in a command line, e.g. "chmod aüs". Enter another
(different) command line, e.g. "chmod axs". Press UP, UP.

Apparently, the bug occurs in about 70% of all tries.

Fix:

unknown.
