From: Michael Welsh Duggan <mwd <at> md5i.com> To: bug-gnu-emacs <at> gnu.org Subject: 24.3.94; CC Mode 5.32.5 (C/l); cc-mode state cache failure leading to bad indentation Date: Thu, 16 Oct 2014 17:12:25 -0400
[Message part 1 (text/plain, inline)]
A consistent c-mode indentation error that causes bad indentation, much cursing, and gnashing of teeth. This occurs in the latest emacs-24 branch (and trunk). From emacs -Q, using the attached file:
[rwuniqsetup.c.before.2 (text/plain, attachment)]
[Message part 3 (text/plain, inline)]
M-x c-toggle-parse-state-debug
C-x C-f rwuniqsetup.c.before.2

C-v
At this point you should see the following in *Messages*:
c-parse-state inconsistency at 46940: using cache: nil, from scratch: ((43406 . 45002))

At this point, indentation is having problems. Try hitting TAB on line
1371, for example. Or line 1374 for a complete failure to indent at
all.
