Thanks, but I don't see any details about the crash: how did Emacs
crash, what were you doing when that happened, etc.  Did I miss
something?

Hello Eli.

Thanks for the quick reply.
I am a favourite of emacs since a long time now.
The program is crashing sometimes repeatedly and some times I can work on
it for hours/days without closing with no problem.
The email I have sent through emacs happen after the crash (I though it
would save the information from the crash). I saw in the internet how to do
the automatic. This (below) is the message that comes from the crash. Maybe
you can interpreted it.

Tell me what more information should I send you.

Best regards

Thanks.  Please run Emacs under GDB, and when it crashes, type this
command at GDB prompt:

  (gdb) thread apply all bt

Then post here everything that GDB displays in response to the above
command.  This will provide a human-readable backtrace that we could
analyze and attempt to understand what causes the crashes.

Please confirm the command in bash
$ gdb emacs

A full recipe would be like this:

  $ cd /path/to/emacs/src
  $ gdb ./emacs
  ...
  (gdb) run

Now use Emacs as usual.  Later, when it crashes:

  (gdb) thread apply all bt

If you don't have Emacs sources installed, the the first command is
not needed, and you can simply say "$ gdb emacs" instead of the second
one.

Thanks.
