CMUCL is an un-officially supported lisp for Elephant. You are the first user who has indicated you were using it since I started working on the project two years ago!

I'd recommend using SBCL.

If you want to spend a little time debugging this, look in src/memutil/ memutil.lisp for the UFFI type definitions for the various FFI functions to manage memory. It may be that it doesn't recognize unsigned-char vs. the keyword version :unsigned-char?

Hi--

I'm getting the following when compiling elephant (both 0.9 and 0.9.1):

Error in function ALIEN::%PARSE-ALIEN-TYPE:
  Unknown alien type: ELEPHANT-MEMUTIL::UNSIGNED-CHAR

CMUCL 19d, with UFFI 1.6.0, running on Linux x86 2.6.18

any ideas?
