I did it :-/ `/bin/ls' coredumped again. Now this is propably a bug in libc.
Its an autobuild install of the date specified. Maybe it can be considered
as too rare but at least its documented now :-/

Looking at the traceback its propably a locale() error.

Haven't found an entry in the PR database yet.

Additional error generated :

trabant% ls -al
Bad pAUX_base
trabant% ls -al

It coredumped just when i typed it as the first command in an xterm in a
just stated X session. It has been used before and after without problems.

The second error (the pAUX_base) also occured with the same actions and is
most likely related.
