How is alloca related to performance?
Excuse me? alloca is used to avoid a malloc/free pair in performance-
critical places, often in inner loops. It's a dirty hack, of course,
but essential for performance reasons.
I mean you should really fix this macro its used all over the code
and it is dangerous.
So is crossing streets used by automobiles, but billions of
pedestrians do that every day, as a performance optimization.
The specific problem with `format' has already been fixed in XEmacs
21.5, I believe (it does not segfault), and probably is slated for the
next release of XEmacs 21.4.
