This problem has noting to do with slime, consult clisp mailing lists, although you probably won't get any help there, since clisp doesn't seem to be actively maintained by anyone.
That's not *entirely* correct, clisp starts fine if I use it manually outside of slime.
Lisp is not like C, no portable program should be able to crash the implementation in such a way. If there's a crash, and no dirty tricks are performed, then the implementation is to blame
Right, I understand that clisp is at fault, I'm just saying that it's slightly misleading to say slime has "nothing to do with it" when it only happens when I use it with slime.
Try clozure cl, it also has better slime support.
I will take a look, thanks!
