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 emacs-pretest-bug@gnu.org mailing list.

I was opening an email with a picture in Wanderlust. Emacs hung, CPU load
went to 100%. I captured the following backtrace (using gdb emacs `pidof
emacs`):

Thank you for your report.

Can you tell where to get that picture, in order to reproduce the
hang?

This is an optimized build.  Too many parameters are optimized out,
and even the backtrace itself is not reliable in optimized builds.

Could you perhaps rebuild Emacs with "-O0 -ggdb -g3", and then show
the backtrace from the same hang?  Also, if you single-step Emacs from
this point, or use `finish', does it loop in endlessly, or does it
remain stuck in append_glyph?  See the section "If the symptom of the
bug is that Emacs fails to respond" in etc/DEBUG for more details
about this.

Finally, please run GDB from the Emacs's src/ directory?  There's a
.gdbinit file there which will show a Lisp backtrace as well.

Yes, please do that as well.

Wow, that's a lot of shadowing!  Is it intentional?

xbacktrace is a command defined by the .gdbinit file in the src
directory that comes with the Emacs distribution.

Thanks.

Thanks.  If no one beats me to it, I will look into this in a few
days, when I have time.

No matter what, thank you very much for your great efforts! I spend almost
half of my waking life with emacs, so I really appreciate the efforts you and
others make.

Best wishes,
Dirk.

Is this still a problem in Emacs 24?
