make-mode.el related crash

[Joshua Varner]

I know that there have been some commits since this version, but in
case it is useful I just had a Makefile shoot into an infinite loop. I
think this string was the problem "# $Header: ", but it is not
reproducable just opening the file. I had this session for only a few
hours, but a fresh emacs on the same file didn't have a problem. I had
even opened other Makefiles containing the same CVS keyword without
any problems.

Version of make-mode.el i had checked out
