This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':

I can't reliably reproduce the bug.
All I can say that the auto-indentation thingymajig in cc-mode stops 
working at
random every 5-15 minutes or so.
I can get it working again by reloading the file I am editing.
When the indentation is broken, pressing enter will leave no indentation
space for braces and such.

it looks like this

if(1) {
foo();
bar();
zot();
}

when it should look like this

if(1) {
     foo();
     bar();
     zot();
}

I'm pretty sure the indentation was working in some previous version,
about two years ago or so, but not in any of the newer versions of Emacs.

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'.
