Subject: C mode fontification took 50 seconds
Date: Sat, 28 Apr 2007 14:35:30 -0400 [thread overview]
Message-ID: <E1Hhrla-0001VV-KF@fencepost.gnu.org> (raw)
Using the latest version of Emacs 22 files, in a 48-line Linux console,
I visited the file xdisp.c and typed C-u 23402 C-n.
Then I typed C-v and waited.
After it had gone on for 30 seconds, I stopped the process and looked
at it with GDB. xbacktrace gives c-syntactic-skip-backward,
c-in-knr-argdecl, c-beginning-of-decl-1, further up
c-beginning-of-defun, further up, c-parse-state,
c-font-lock-complex-decl-prepare. This was called
from font-lock-fontify-keywords-region.
It looks like c-in-knr-argdecl has the infinite loop.
After I continued, it eventually finished, but yuck!
This is reproducible.
