Bug triggered by compilation-mode + font-lock, XEmacs 21.4.11.

Hi, I'm compiling my BSD. M-x compile "cd /usr/src && ./build.sh -U -O /usr/obj -T /usr/obj/tools -V NOCLEANDIR=yes -V MKOBJDIRS=no -V NOINCLUDES=yes distribution" RET . About fifteen lines into it, a really long mkdep output line gets printed to the compilation buffer. XEmacs crashes. I'm not 100% sure that this wasn't triggered by compiling with optimisation; I'll recompile tomorrow and find out. My compiler is normally GCC3, my CFLAGS normally "-march=pentium4 -mfpmath=sse,387 -momit-leaf-frame-pointer -O3 -ffast-math" . Lisp backtrace follows: re-search-forward("^[^:\n]+-[a-zA-Z][^:\n]+$" 25533 t) (if (stringp matcher) (re-search-forward matcher end t) (funcall matcher end)) (and (< (point) end) (if (stringp matcher) (re-search-forward matcher end t) (funcall matcher end))) (while (and (< ... end) (if ... ... ...))
