This has been resolved [in the latest patches to CFFI for ABCL][1]

[1]: ​http://slack.net/~evenson/abcl/cffi/cffi-abcl-20121021a.patch

A [version of this patch has been committed to the master CFFI repository][2], so this change will make it into the Quicklisp distributed version when there is a new release of CFFI.

Sorry, I am testing on quicklisp 2013-01-28 and see that CFFI hasn't been updated with required fixes yet.
