Greetings, I believe I found a bug (or at least a change) in the behavior of expr in coreutils-6.8.
Formerly this command: expr 20x11-common_process-args : '[[:alnum:]_-]\+$' returned the value 25. As of coreutils-6.8, that command returns an error: /opt/bin/expr-broken 20x11-common_process-args : '[[:alnum:]_-]\+$' /opt/bin/expr-broken: Unmatched [ or [^ In case you're interested, I detected this defect in the /etc/X11/Xsession script, where `expr' is used to determine what scripts to source.
