Hello.

This is one of those vague bug reports that aren't easy to reproduce.
After using Emacs for some time (several hours, more than 4) and editing
many C++ and C files, indentating breaks down.  This manifests itself
that most lines get indetated at column 0.  Doing C-c c-s on those lines
shows topmost-intro.  even if they should be inclass or statement.

Restarting Emacs fixes everything.

Hello, Jan,

Hmm.  It's also, unfortunately, one of these bug reports that are
difficult to respond to in a helpful manner.

"Most"?  Any chance you could post a fragment of a buffer (say, 20 - 60
lines starting near a beginning of defun) with the syntactic analysis of
each line (Use C-u C-c C-s on each line)?

OK.  Now some more details, please!

(i) Have you ever noticed this bug happening on earlier Emacsen, in
  particular Emacs 23.1?
(ii) Does this bug happen every time you use Emacs this long, or only
  sometimes?  If the latter, how often (10%, 50%, 90%)?
(iii) Do you think there might be any connection with some of the more
  unusual minor modes you've got switched on?  Things like
  auto-encryption mode?

When Emacs reaches this broken state:
(iv) Are all C(++) buffers in this state, or only some?  Any correlation
  with how many edits have been done on a buffer, or how long it's been
  loaded?
(v) What about indentation in a freshly loaded file?
(vi) Will M-x c-mode or M-x c++-mode clear the problem?
(vii) Does reverting (M-x revert-buffer) a file fix indentation?
(viii) Does killing and reloading a file fix indentation?
(ix) Does intentation gradually deteriorate at around 4 hours, or does it
  break suddenly?
(x) Do all CC Mode buffers break at the same time, or is it a "creeping
  death"?

I realise how tedious it is to reproduce the broken state, but answers to
these questions might suggest a line of attack on the bug.  Also, please
post any further thoughts you've had about it.

Just one other thing: Could you please post a dump of your CC Mode
configuration (C-c C-b in a C(++) buffer).  Thanks.

> Restarting Emacs fixes everything.

Well, that's one thing to be grateful for.  :-)

Ok, here are some answers.

No.

100%.  If I just keep editing it eveentually breaks.

No, this doesn't seem to have any effect.

It is a pre buffer breakage.  One buffer usually gets borken first, while the 
others are ok.  It is the one that I've changed/edited the most in.

> (v) What about indentation in a freshly loaded file?

No problem.

> (vi) Will M-x c-mode or M-x c++-mode clear the problem?

Yes.

No.

Suddenly.

Only one at the time.

Hi, Jan,

Time for a top-post.  ;-)

All your answers to my questions are consistent with a bug in
c-parse-state (don't ask!).  I recently enhanced and severely optimised
this routine (it contains a cache) to deal better with certain types of
non-unusual source files.  If this cache is getting corrupted, it could
easily foul up a buffer's indentation.

Would you try one more thing, please: when you reach this buggy state
again, would you please do

    M-: (c-state-cache-init)

, and tell me if this clears the buggy state.

Thanks!

No, it does not.  Run with Emacs taken from trunk 2010-02-24, around

Yeah, I've been noticing the same problem a lot recently , and
(c-state-cache-init) doesn't seem to help.

Neither does re-invoking c++-mode (which in the past I've found is often
a good way to clear indentation bugs due to c++-mode caching bugs).
Deleting the buffer and re-visiting the file is the only way I've found
to get things working again.

It does seem to always occur somewhere following use of template'd
types though, so I imagine it's probs with the < and > chars.

[The annoying thing is that while it's very repeatable at the time it
occurs, it doesn't repeat for different emacs sessions, so I'm not
entirely sure how to go about reporting the bug...]

Reinitialising a CC Mode doesn't clear text properties from the buffer.
Perhaps it should.

As always.  These little characters are horrors to deal with in C++ Mode.
Their treatment is gradually improving.

In particular, I fixed some "silly" bugs concerned with them and
committed the fix yesterday evening (UCT+2).  Hopefully, things will run
more smoothly from now on.

Bob did so splendidly with a dribble file and CC Mode configuration
(generated by C-c C-b).  Anyhow, it might be working properly now.

Hello.

FWIW, this bug is still present in the trunk.  I see it 5-8 times per day.
Revert buffer sometimes work to get back on track, but for the majority of 
cases, I have to kill the buffer and reopen the file for cc-mode to work again.

	Jan D.

Hi, I've been using cc-mode every day for the past few years at
work, and I don't recall seeing this bug either in Emacs 24 or 25.  Has
anyone reproduced this lately?

I think it's very likely that the latest fixes by Alan in CC mode
nailed this one for good.

OK, I'm going to mark this one as doneunreproducible - it may have been
fixed some time in the past, or by these recent fixes you refer to.
I'll keep an eye out for this myself during my normal work, and re-open
this if I or anyone else starts seeing this again.

Thanks.  I think this bug (which was definitely real) got fixed as a side
effect of fixing something else, and this happened quite a long time ago.
