Emacs 21.3/21.4 seems to reproducibility freeze when
typing an unbalanced parenthesis in c++ mode inside a
pair of brackets - i.e. something like "if ( foo( )" -
if the corresponding line is not yet automatically
indented, and if it is located inside of a
sufficiently big file.
You can obtain my file to reproduce it at:
http://www.theorie.physik.uni-muenchen.de/~munk/freeze3.cpp
To reproduce the freeze,
- open it with emacs -q
- turn on global-font-lock-mode, and wait some
seconds.
This always freezes my emacs. I tested it on debian
sarge and suse 9.something (emacs 21.3), both also in
a console with "emacs -nw ..." Furthermore, I did not
only experience it with this specific example file,
but also with several others, always in a set up as
described in the first paragraph. It seems to be
independent of the "Font Lock Support Mode" (I tested
jit lock and fast lock).
I don't have access to the current CVS emacs, so I
don't know it is still present there. The output at
the bottom is what "report a bug" in emacs produced
after opening the file, just some seconds before the
freeze.
Cheers,
Tobias

I can reproduce this bug with Emacs 21.4 but not with the CVS version,
so it appears to have been fixed. Thanks for the report!
