I put the snippet into a file /tmp/snippet.cc, and said: ./src/emacs -Q /tmp/snippet.cc But I was unable to reproduce the problem -- the file displayed as normal for me, and Emacs didn't use 100% CPU. Are there any additional steps necessary to reproduce the problem? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
