[slime-devel] strange thow starting slime... - slime-devel - mailman3.common-lisp.net

9 Jun 2010


      I'm running slime /w sbcl on an ubuntu 10.04 amd64 machine. I use 
clbuild to generate lisp environments for each project I work on. Slime 
starts normally when I have a fresh checkout of slime and a fresh build 
of sbcl in a clbuild instance, compiled from the sbcl in the ubuntu 
lucid package pool, but only on the first invocation when there aren't 
any fasls. Upon subsequent invocations, when the environment tries to 
start up from the fasls generated previously, I get swank throwing to 
sldb with only an abort restart, which kills the slime startup entirely 
when selected. Previously slime was throwing the same warning, but it 
offered other restarts that allowed swank to start, and slime to 
connect. The sldb and inferior lisp buffers follow:
=================
;; inferior lisp:
(progn (load 
"/home/fade/SourceCode/lisp/clbuild/source/slime/swank-loader.lisp" 
:verbose t) (funcall (read-from-string "swank-loader:init")) (funcall 
(read-from-string "swank:start-server") "/tmp/slime.2349" :coding-system 
"utf-8-unix"))
This is SBCL 1.0.39.2, an implementation of ANSI Common Lisp.

... if I remove all relevant fasls and force the environment to 
recompile everything, I can start slime again, once. It would be great 
if somebody could point me toward a permanent fix for this. I should 
also note that I do not see this problem at all running Clozure Common 
Lisp against the same clbuild instance, so this looks like it may be a 
problem in SBCL, but after pfaffing about in the inspector for quite 
awhile, I still haven't narrowed down the problem -- debugging PEBCAK to 
be sure, but any help would be greatly appreciated!
Kind Regards.,
Brian
