here is an example (from http://swtch.com/~rsc/regexp/regexp1.html) python -c 'import re; num=25; r=re.compile("a?"num+"a"num); r.match("a"*num)' At work I have seen a real world case of a regular expression which ran for minutes rendering the application unresponsive. We would have been glad to be able to interrupt the regular expression engine and getting a traceback.
