WITH-FOREIGN-POINTER expands to WITH-ALIEN on SBCL, which performs stack allocation.

But when I run it using SBCL on Ubuntu 10.10 32bit, it complains about some value not being of type (MOD 536870909). Is this a deliberate limit on the part of CFFI or SBCL? If so where can I adjust this limit?

It's an SBCL limit (64 MB?). I don't know if you can adjust it but someone on sbcl-devel should know. I'm surprised it's that big, though. Shouldn't it be much smaller?
