It's important that this doesn't come back! =20 In fact, on my machine with the default stacksize of 2048kb, = test_re.py already exercises this bug. (Goes away if I do an "unlimit", of = course.) So testing for this deterministically is always going to be dependent = on the platform. How large do you want to go (reasonably)? - although I guess core dumps should be avoided...

afaik, there was no test in the standard test suite that included run-away recursion...

what test is causing this error?

(adding a print statement to sre._compile should help you figure that out...)
