[Message part 1 (text/plain, inline)]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing
list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Try this:

C-x o C-x h <backspace> T o p ( C-u 2 5 6 
0 0 SPC <backspace> <backspace> <backspace> <backspace> 
<backspace> ) <backspace> SPC ) <backspace> SPC ) <backspace> 
SPC ) <backspace> SPC ) C-a <right> <right> <right> 
<backspace> <backspace> <backspace> C-e <backspace> 
) <backspace> <backspace> ) <backspace> SPC ) <backspace> 
<backspace> )

There seems to be an arbitrary limit on the parenthesis
matching, which is antique and useless.  Please remove
it.



If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1/etc/DEBUG for instructions.

See option `blink-matching-paren-distance'.

And see the discussion of bug #5122 (this seems to duplicate that).

You can set blink-matching-paren-distance to nil. The default limit
has already been increased for Emacs 23.2.

I see that you closed this bug (#5709).

OK, but #5122 should remain open, to make clear that this still isn't solved
satisfactorily. Being able to customize it and upping the default value are not
complete answers.

As Stefan said near the current end of the #5122 thread:

  Clearly, the only real answer is to get rid of
  blink-matching-paren-distance.  We could try and do that,
  maybe using while-no-input.

There is also other discussion in that thread about the general problem and what
might be done about it.
