[slime-devel] Lisp connection closed unexpectedly

[J. Bromley]

I am having a problem with SLIME getting disconnected from the Lisp
process when requiring certain libraries. I am using clbuild to manage
my Lisp implementation and SLIME itself. The problem is that when I do
(require 'cl-opengl) in SLIME, I get the message "Lisp connection
closed unexpectedly: connection broken by remote peer" in the
mini-buffer area. I set swank:*log-events* to t and tried, and
unfortunately that was not terribly helpful. Here are the lines
generated by the require cl-opengl line:

=====
dispatch-event: (:EMACS-REX (SWANK:OPERATOR-ARGLIST "require"
"COMMON-LISP-USER") "COMMON-LISP-USER" :REPL-THREAD 15)
send-event: #<SB-THREAD:THREAD "repl-thread" RUNNING {10030E2AE1}>
(:EMACS-REX (SWANK:OPERATOR-ARGLIST "require" "COMMON-LISP-USER")
"COMMON-LISP-USER" 15)
wait-for-event: (COMMON-LISP:OR (:EMACS-REX . SWANK::_)
(:EMACS-CHANNEL-SEND . SWANK::_)) NIL
dispatch-event: (:RETURN #<SB-THREAD:THREAD "repl-thread" RUNNING
{10030E2AE1}> (:OK "(require MODULE-NAME &OPTIONAL PATHNAMES)") 15)

dispatch-event: (:EMACS-REX (SWANK:LISTENER-EVAL "(require 'cl-opengl)
") "COMMON-LISP-USER" :REPL-THREAD 16)
send-event: #<SB-THREAD:THREAD "repl-thread" RUNNING {10030E2AE1}>
(:EMACS-REX (SWANK:LISTENER-EVAL "(require 'cl-opengl)
") "COMMON-LISP-USER" 16)
/Users/jay/Applications/clbuild/clbuild: line 450: 11820 Trace/BPT
trap          ${lisp} $common_options $eval "$require_asdf" $eval
"$set_central_registry" $eval "$EXTRA_CLIM_FEATURES" "$@"

Process inferior-lisp exited abnormally with code 133
=====

I am using the following software:

 * Mac OS X 10.6.4
 * SBCL 1.0.42.52 (checked out by clbuild and built)
 * GNU Emacs 23.1.50.1 (x86_64-apple-darwin10.2.0, NS
apple-appkit-1038.25) from MacPorts
 * SLIME from CVS via clbuild
 * cl-opengl from git via clbuild

I have looked at line 450 of clbuild and it is just the call to launch
SBCL. I find no more information about the Trace/BPT trap. I have also
tried to find the meaning of the exit code, but have been
unsuccessful. If I run clbuild lisp (which runs SBCL without SLIME)
the require works fine. Obviously, SLIME provides a much nicer working
environment, so it would be great to get it working.

 I would greatly appreciate any suggestions on possible solutions or
about how to debug this further.

Thanks and regards,
