I'm having problems running sbcl. I'll try to be as concise as possible:

I start SBCL (via SLIME in a terminal), start my program, and after sometime, SBCL crashes, with a message like this:

Argh! gc_find_free_space failed (first_page), nbytes=8.

Googling for an answer didn't work at all. I'm using the latest CVS SBCL version, under Debian (kernel 2.6) in a Xeon Machine with 2GB RAM.
Do you know what's the reason of this error? Any solutions?
Thanks in advance for your help
