That's only for developers trying to build things on top of cmucl.

Well, I managed (sort of) to create the same problem here in my laptop
(FC1). I'm testing kernel 2.6.4 and that is enough to kill cmucl. No
workaround so far, no tips or tricks to share. You are not doing
anything wrong, I think. It's just that there is something different in
your system that tickes a problem in cmucl. 

CMUCL is _VERY_ finicky with the system it is running on. Over time I've
had nothing but troubles. 

At least for the CM/CLM/CMN world I'll be looking into moving over to
SBCL. That one seems to work a lot more reliably (it still starts under
2.6.4). And it is more of a possibility to rebuild it (there are even
source rpms distributed with their releases!). 

Sorry to not have better news.
