Re: SBCL and Ilisp

Hi Christophe,

I saw your note about this. I recently fixed the gcl regexps in ilisp
and thought I might try my hand at this problem.

In short, the trouble is with sbcl, not ilisp. In sbcl, if the file
/tmp/foobies does not exist,

* (load "/tmp/foobies" :if-does-not-exist nil)

NIL
* 

but if /tmp/foobies.fasl doesn't exist,

* (load "/tmp/foobies.fasl" :if-does-not-exist nil)

debugger invoked on condition of type SB-INT:SIMPLE-FILE-ERROR:
  The file "/tmp/foobies.fasl" does not exist.

Within the debugger, you can type HELP for help. At any command prompt
(within...

Ilisp tries to load compiled versions of the files first, with the
:if-does-not-exist key nil. It then loads the uncompiled versions.
The drop into the debugger before configuration is done confuses ilisp
completely.

This kind of thing is usually easy to spot by setting comint-log t,
which fills a buffer with the raw communication between ilisp and the
inferior lisp process.

I've cross-posted this to sbcl-devel, in case someone there remembers
how the trouble was introduced.

Best Wishes,

Greg Wright
