Thanks for the testing. The segfault appears to be related to the foreign
function interface; the generational GC works fine now.

I've therefore released libsigsegv 2.10 and committed the change into clisp.

Regarding the segfaulting test, you may follow up with Sam on clisp-devel.
My first, uninformed suspicion is that it's related to the representation of
NULL pointers or stack addresses on this platform (I remember something about
bit 31).
