Gnus/5.11 (Gnus v5.11) Emacs/22.0.50 (gnu/linux)
Upon opening, some makefiles are causing Emacs to begin 100% CPU
utilization for an unacceptably long time (minutes).
- Open a new buffer and put it in make-mode.
- Type "foo:" and a new line.
- Type " echo *".
- Keep typing asterisks. After each asterisk, Emacs hogs the CPU for
an increasingly long time.
Thirty-two asterisks causes emacs to hog the CPU (uninterruptibly) for
over a minute on a 3GHz P4, at which time I lost patience and killed it.
This problem manifests with CVS 2005-05-17, but not with CVS 2005-04-28. I note
that Daniel Pfeiffer made changes to make-mode.el on the 13th and 16th of this
month; possibly one of these commits has introduced the problem.
The real-world makefile that brought this bug to my attention is attached below.
