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:



Emacs build core-dumped during unexec() / memcopy().
See attached file 'emacs-22.1-with_coredump.tar.gz'.

The archive contains the coredump at  'emacs-22.1/src/core.433'.
The coredump was generated from       'emacs-22.1/src/temacs'
                    with command       'temacs -batch -l loadup dump'.
More information can be found in      'emacs/pkg_*.log'.

Unfortunately, the bug seems to appear randomly.
I hope the given information is enough.


Thanks for your concern.

Regards,
Pierre-Louis ESCOUFLAIRE
