Takes several minutes to load 512k C header |
Date: |
Mon, 01 Sep 2008 12:16:14 +0100 |
I try to load the attached file (when un-compressed). It's 512k of
text, but I have a fast multi-GHz machine with GBs of spare RAM etc. and
I can load 20+Mb .txt files in emacs just fine normally.
Loading this generates several minutes of non-responsiveness.
HTH,
Michael.

Alan's fix isn't on the Emacs 22 branch, but it's too late to check it
in for Emacs 22.3, I think.
Michael: in the meantime, you could try to apply the patch to your
personal version of cc-engine.el (I believe it applies cleanly):
http://cvs.savannah.gnu.org/viewvc/emacs/lisp/progmodes/cc-engine.el?root=emacs&r1=1.56.2.10&r2=1.56.2.11&diff_format=c
