Well, an infinite hook recursion still shouldn't make Emacs crash. The backtrace reminded me a bit about the known gc recursion bug that I can't remember the recipe for right now -- it was something about if you (setcar foo foo), then Emacs will segfault when trying to gc? I forget the details, but it's in the debbugs somewhere. :-) -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
