Hi,

I have been running into a problem off and on for several weeks that seems to come from an interaction between slime and SBCL resulting in an infinite loop requiring me to killall sbcl to stop it. Until now I haven't been able to isolate it to a simple case. Here's one:

• I start up emacs (21.4.1)
• I start up M-x slime (2007-03-29).
• In the slime-repl I type the bogus command 'lt' <enter>.

The speaker starts beeping and slime and emacs are utterly hung. I have to kill sbcl which releases emacs to keyboard commands.

When I hit C-x b a window opens up at the bottom of emacs which shows the following:

iswitch {imagelib.lisp,*scratch*,*Messages*,*Compile-Log*,*slime-events*,*sldb sbcl/0*,*sldb sbcl/0*<2>,*sldb sbcl/0*<3>,... where the number inside the braces keeps incrementing forever <4>,...,<5>... etc.

I will attach a screen capture in case it isn't clear. I can't navigate to that window and copy it.

The steps I've taken to isolate the problem are to update sbcl to todays version (1.0.4) compiled from source (from 1.0.3 - both act the same way), and to remove my .sbclrc file.

Any ideas how to debug this?

Thanks

I have a feeling the attachment may have blocked this from reaching the list, so I'm resending it without the image. I also managed to get into the *Messages* buffer and here's what I found there:

error in process filter: sldb-mode: Symbol's function definition is void: delay-mode-hooks error in process filter: Symbol's function definition is void: delay-mode-hooks ; pipelined request... (swank:debugger-info-for-emacs 0 10) error in process filter: sldb-mode: Symbol's function definition is void: delay-mode-hooks error in process filter: Symbol's function definition is void: delay-mode-hooks ; pipelined request...

This repeats over and over - 51 times.
