Re: slime + clisp + emacs: server disconnects

23 Jul 2019

      I have sbcl too (switched to it after the clisp shenanigans started upon upgrading to v2.24):
It does *not* crash, and I'm perfectly happy using sbcl.
I was just impelled by curiosity to try and figure out what's wrong on the clisp side.

Have you considered switching to Steel Bank Common Lisp (SBCL) to see
if it
also crashes?

Well, your clisp just happens to crash on that.
I understand that :), but the purpose was to gain some insight into
how or

why it's happening.
Perhaps I can hack the swank loading procedure to avoid this, for
instance.But I'd need to understand the situation beyond the simple
observation that there's a crash, hence the mailing list message.

It says that Clisp crashes with a segfault, nothing to do with
slime.

It does say that, but a follow-up:
If I run through the procedure described at the end, of starting
swank

from within clisp, there are no crashes with swank-v2.20 (rather than
2.24).

I do get a warning in emacs to the effect that swank (2.20) and
slime

(2.24) versions don't match, but once I confirm that the crashes go
away.

So this same clisp installation works fine with swank 2.20 and
not

swank 2.24, meaning that some change in the latter is what's causing
this.

Process inferior-lisp segmentation fault
--- buffer ends ---
More information:

starting clisp in a terminal all on its own seems to work

fine;
...
I haven't had segmentation faults using it in isolation from slime.
...
...
...
...

I tried to start the server from within clisp and connect

to it:
...
...
...
...
...
(a) rlwrap clisp
(b) (load
"~/quicklisp/dists/quicklisp/software/slime-v2.24/swank-loader.lisp")
...
...
...
...
(c) (swank-loader::init :reload t)
(d) (swank:create-server :port 7000)
(e) from within emacs: M-x slime-connect with localhost and
port
...
7000
...
...
...
...
Same behavior as before: I get connected, get to make a few
evaluations, get disconnected.
...
...
...
...
This time around rlwrap tells me (in the terminal where I
started
...
clisp):
...
...
...
...
rlwrap: warning: clisp crashed, killed by SIGSEGV
