Hi,
I have several debian accounts with email. One such account started
having difficulty. When trying to send an email while in an RMAIL buffer
using C-c C-c, emacs crashes unexpectedly with this error:
emacs[0x541b30]
emacs[0x50bc8f]
emacs[0x50c003]
...
Illegal instruction

It probably is some kind of interaction with the underlying linux mailer
that is killing emacs, but it would be nice to have some graceful exit,
and perhaps some chance of debugging the problem, with my limited
knowlege and abiliti3s.

Thank you.

Which version of Emacs is that?

In any case, those addresses can only be interpreted on your machine.
Can you run Emacs under GDB, and when it crashes, produce the
backtrace and post it?

Could you try to reproduce this in gdb to produce a backtrace?

Hi Eli,

The version is GNU Emacs 24.4.1. I have included backtrace at end of message.

Thanks.  Emacs 24.4 is very old, I suggest to upgrade.

Sounds like some problem with the GnuTLS library, so I suggest to
upgrade that as well.

I see no indications here that it's an Emacs problem.

Rather the (self-compiled?) GMP library.

Yup.  That it's in /usr/local seems to point to a self-compiled library.

In any case, this doesn't seem to be an Emacs bug, so I'm closing this
bug report.
