[rev 109796]
This crash, which happens rather frequently, is something introduced
quite recently. My last bzr build (in June, IIRC), using the same
GNU/Linux environment (gcc 4.6.2, KDE 4.8, Qt 4.8), didn't show this.
It seems that the crash happens if I look at e-mails with CJK
characters (using Mew), then composing a simple e-mail, then trying to
send the e-mail. I have no exact recipe to reproduce, sorry.
I still have the emacs process in gdb, so please advise how to
proceed.
Werner

Looks precisely like bug#12251. Hopefully, Eli can tell you how to proceed.
Please keep it in gdb.

Indeed. I've forgotten to describe the symptoms if not running under
gdb, and they are the same (visible bell while moving the mouse or
pressing any key, but no reaction otherwise; I had to kill Emacs, or
it crashed after some time).

Meanwhile could you try the patch I earlier sent to Sam. I'll attach it.
Basically, it should help to find the bug earlier.

Just now I've got a crash, but I'm not sure whether it belongs to this
bug report. Since I'm using Martin's patch, I'm reporting it here.
The crash happened after composing an email with mew, then trying to
send it with C-c C-c.
I still have the process. Anything else I can investigate?

Yes, please. We need to understand why it segfaulted.

What does the following show?
(gdb) p *b->base_buffer
> (gdb) p undo_list
> No symbol "undo_list" in current context.
undo_list is a name of a struct member, not a variable.
Thanks.

I just sent some requests.
In any case, I don't think this crash is relevant to this bug report:
there's no mouse-highlight anywhere on the call stack. I suggest to
file a separate bug report.

I'm now running an Emacs compiled from a freshly checked out bzr on
Sept. 6th, and it seems to be stable again. I suggest to close this
bug.
