Nix writes: If they're partially broken they might still work properly? ;-) I believe that is true. There are some very old comments about magic free hooks, but IIRC the code that used them is also inside the comment.... There was a long-standing bug in "large string allocation", where the cons counter didn't get bumped properly for large strings. It was possible to do something like `(while t (make-string 1000000 ?A))' and crash XEmacs in short order. Martin Buchholz submitted a patch for that, which I applied based on my limited understanding that it was correct and the strength of Martin's reputation for finickiness. Looking at the large strings first is insider information, not magic, but it might save you some work. However, the bug was not that they never get collected---if something else triggered a GC they got collected. I wouldn't bet on it being related, but you have to start somewhere.... _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
