Hi all,
In bash:
# sbcl --core sbcl.core-with-swank This is SBCL 1.0.30, an implementation of ANSI Common Lisp. More information about SBCL is available at http://www.sbcl.org/.
SBCL is free software, provided as is, with absolutely no warranty. It is mostly in the public domain; some portions are provided under BSD-style licenses. See the CREDITS and COPYING files in the distribution for more information. * (swank:create-server :port 49153) ;; Swank started at port: 49153.
49153 * (swank:stop-server 49153) #
sbcl dies, which I obviously don't want it to.
My core includes the latest slime/swank from CVS, on a Debian (Lenny) box.
I need to be able to stop swank the server cleanly, whilst leaving sbcl running.
Is this a (serious) bug or am I missing something?
Regards,
Seb

That's a bug, it was killing the wrong thread. Fixed in CVS. Thanks for the report!

Thanks for the super-quick response, but...
... having checked out the fix, I can no longer build the core. It never used to produce this much output, and, needless to say, it didn't use to fail:

It's working fine now. Thanks a lot :)
