I have a regular expression that is approximately 100k bytes. (It is basically a list of all known norwegian postal numbers and the corresponding place with | in between. I know this is not the intended use for regular expressions, but it should nonetheless work.
the pattern is ur'(N-|NO-)?(5259 HJELLESTAD|4026 STAVANGER|4027 STAVANGER........|8305 SVOLVÆR)' The error message I get is: RuntimeError: internal error in regular expression engine -- http://mail.python.org/mailman/listinfo/python-list
