--- Comment #9 from firas <firas....@gmail.com> --- The implementation on regex101 is returning a match with start index 21 and end index 22, which then means it tries to find another match on index 22. It finds another one, again, at index 21-22, and keeps repeating this process indefinitely. I'm not sure why this happens. -- 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
