Subject: bug#15648: 24.2.50; gnutls SSL connection to IMAP server causes emacs to crash completely
Date: Fri, 18 Oct 2013 14:29:04 -0400 [thread overview]
Message-ID: <21089.32240.198931.971000@consult.pretender> (raw)
This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgment at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
I am using gnutls within the vm (viewmail) mail reader (vm-version
8.2.0b) to read email over IMAP-SSL under nt Emacs 24.2.50.1 in
Windows 7
Emacs gives me the following error in the message line before immediately
crashing the entire emacs process:
GnuTLS error: #<proces IMAP over SSL>, -64
The Windows crash both then gives me the following error:

I do not believe this is a problem with vm (viewmail) since all works
well when I use an external program (stunnel) to create the SSL
tunnel. The problem only happens when I use the internal GNUtls
capability to create the SSL tunnel.
Even so, it is surprising to me that the entire Emacs app crashes - I
have beena heavy Emacs user since 1984 and I don't believe I have ever
had it crash! (kudos to emacs for reliability)
Debugging wasn't easy since I needed to 'catch' it right before the
crash and set a breakpoint there. It turns out that it crashes when
evaluating the declared c-function "gnutls-boot" which is an argument
to "gnutls-message-maybe" called from the function gnutls-negotiate in
gnutls.el
(gnutls-boot process type params)
where:
process = #<process IMAP over SSL>
type = gnutls-x509pki
params = (:priority "NORMAL" :hostname "imap.mydomain.org" :loglevel 0 :min-prime-bits 256 :trustfiles ("/usr/ssl/certs/ca-bundle.crt") :crlfiles nil :keylist nil :verify-flags nil :verify-error nil :verify-hostname-error nil :callbacks nil)
(gnutls-boot gnutls-x509pki
Here is what I got from the Emacs debugger:
* (gnutls-boot process type params)
* (setq ret (gnutls-boot process type params))
