You've got a fast machine, perhaps. :-) > Are you still seeing these issues in recent Emacs versions? I still see them. What's more, I know exactly what's causing the hangs. In forward-paragraph, a regular expression is formed by concatenating the major mode's paragraph-start and paragraph-separate with a few other things. In CC Mode (at least), this gives rise to ill-formed regexps with adjacent sub-expressions which each can match the empty string, or arbitrary numbers of spaces. When there fails to be a match, the regexp engine tries in every possible way to find a match, and thus failing to find one takes a long time. I started work on a library to fix ill-formed regexps in 2015, and after a long gap, recently re-started work on it. Although there is still quite a bit to do on it, I can see my way to finishing it. This would fix the cause of the bug properly. Perhaps I may be able to make the current state available on a git branch under scratch "soon". So, can you leave this bug open, please? > -- > (domestic pets only, the antidote for overdose, milk.) > bloggy blog: http://lars.ingebrigtsen.no -- Alan Mackenzie (Nuremberg, Germany).

I think I've found it. In foward-paragraph (paragraphs.el) L+37,
sp-parstat is bound as follows:
(sp-parstart (concat "^[ \t]*\\(?:" parstart "\\|" parsep "\\)"))
, where parstart and parsep are, basically, paragraph-start and
paragraph-separate.
In CC Mode, paragraph-s{tart,eparate} both start with "[ \t]*". So when
a regexp search for sp-parstart is done on a non-matching line beginning
with spaces, there will be a lot of alternative ways for the regexp
engine to attempt to match the spaces before finally giving up on the
line.
The optimal solution to the bug would involve intelligently combining
parstart and parsep into a safe regexp. I don't know how to do this
(suggestions welcome).
The alternative seems to be to search for parstart and parsep separately
inside an `or' form.
Any thoughts?

I don't see the difference between 24.3 and current master. On both of
them, the behaviour is the same. The spaces get inserted normally, up
to column 72, then the display freezes. Some long while later (several
minutes), the display catches up again. This is with point in column
~500. (Both of my Emacs builds were with optimisation and without
debugging info. Your build was without and with.)
A quick use of the profiler shows that forward-paragraph is taking ~87%
of the total CPU. There'll be a reason for this. I'll have a look at it.

Incidentally, that doc string
If this variable is t, Emacs asks the window manager to give the frame
intermediately its normal size whenever changing from a full-height or
full-width state to the fully maximized one and vice versa.
doesn't read well. The "intermediately" in that position isn't English!
Perhaps something like the following would be better:
If this variable is t, Emacs first asks the window manager to give the
frame its normal size, and only then the final state, whenever changing
from a full-height or full-width state to the fully maximized one and vice
versa.

With current trunk/master and emacs -Q evaluate the following form
(add-hook
'c-mode-hook
'(lambda ()
(turn-on-auto-fill)
(set (make-local-variable 'fill-column) 72)))
and visit ~/src/xterm.c. Go to the end of that file, move a few lines
backwards so that point is at the beginning of some non-empty line
within the doc-string of `x-frame-normalize-before-maximize' (which is
coded as a C comment). Now keep the SPC key pressed. Here Emacs
consumes the entire available CPU and eventually redisplay gets stuck
completely. This used to work without problems in Emacs 24.3.
