Adduser devel - Mar 2012 - Bug#666435: invalid error message when subprocess killed by signal

Package: adduser
Version: 3.113+nmu1
Severity: minor

If you happen to run into the userdel segfault (#660406), then you get
an error message like this:

/usr/sbin/deluser: `/usr/sbin/userdel foo'' exited from signal 139.
Exiting.

This should be signal 11 instead.  The description of the Perl system
function suggests to use ($? & 127), instead of $? & 255 currently in
use.
