It might not have anything to do with that bug at all - I was just going back and seeing if that bug had been fixed. Create a Makefile with the contents: all: @echo [insert 5000 chars] Run emacs -Q and do Tools > Compile... RET and I see Emacs create the *compilation* window and insert chunks of the echo output. 23.0.94 takes 20+ seconds to complete it and is pretty much unusable during that time. 22.3 takes 1 second. Looking back at earlier pretests, this also applies to 23.0.91. Thanks, Simon.

Joakim, could try to come up with a faster regexp?
