[slim-vim] ecl-slime crashing on me

[Larry Clapp]

Brad,

I pulled a fresh ecl-slime, and a fresh Slime, and ecl-slime crashes
on me on the first expression evaluated.

In clisp:

- load swank-loader
- run (swank:create-server :dont-close t)

In Vim:

- disable ecl-repl
- start Vim in the ecl-slime directory, load *.vim and *.lisp
- source ecl-slime.vim
- open a new buffer
- type ,sc to connect to Swank
- type (+ 1 1)
- type ,x to execute
- wait

and a few seconds later clisp prints a few thousand lines of

DISPATCHING:
(:WRITE-STRING
 "READ: \"(:EMACS-REX (SWANK:INTERACTIVE-EVAL \\\"(+ 1 1)\\\")
 \\\"#:slime\\\" T 1)\"
 DISPATCHING:
 DISPATCHING:
 DISPATCHING:
 DISPATCHING:
 DISPATCHING:
... etc
 ")

and Vim crashes to the ECL debugger.

The clisp backtrace:

> ;; Event history end.
> ;; Connection to Emacs lost. [
> ;;  condition: SYSTEM::STORE-SCHAR: index 8000 should be less than the length of the string
> ;;  type: SWANK::SLIME-PROTOCOL-ERROR

[ Note: clisp didn't crash, I pressed ^C ]

If I don't load *.vim and *.lisp, and just source ecl-slime.vim, then
,sc segfaults on me.

I assume this is not what you get.  :)  What Lisp do you use, how do
you load ecl-slime, etc?
