LI> How do you replicate this error?

Real simple.

$ cat /tmp/b
make -k
perl -nwe 'next if (length) < 32; print "$ARGV:$.:$_"; $bad=1;END{die
if $bad}' 201204CS
201204CS:1:.....................................
201204CS:55:14:00~17:00 (13:50開始開放入場)
201204CS:108:.....................................
Died at -e line 1, <> line 108.
END failed--call queue aborted, <> line 108.
make: *** [check_length] Error 22
$ emacs -nw -Q -eval '(compile "cat /tmp/b")'

See how the second error line is a different color?
