When I try looking at this message, I don't get a hang, unfortunately. I've tried in Emacs 27, and I don't get it there, either. Your simpler report, that (looking-at gnus-supercite-regexp) "> ___________________________________________________________________________" (without the quotes) hang, I'm not able to reproduce either (on Emacs 27.1 or Emacs 28). Anybody guess what's going on? Our systems look pretty similar, but I'm on Debian, and the reported is on Arch. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
