--- Comment #1 from Philip Hazel <p...@hermes.cam.ac.uk> --- In order to try to reproduce this with pcre2test, I need to know what the subject line is that was being matched against that regex, and whether it is expected to match. It may be that you just have a very large search tree that is taking a very long time to search. This is the most common cause of reports of "looping". On the other hand, your regex doesn't look pathological at first sight. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
