[Cffi-devel] What is wrong with this 2d array of pointers

I was hoping someone could look at this and help me debug it. I'm getting: (FOREIGN-ALLOC :POINTER :INITIAL-ELEMENT (NULL-POINTER)) is not of type SB-SYS:SYSTEM-AREA-POINTER. when I run it. (foreign-array-alloc #2A(( (foreign-alloc :pointer :initial-element (null-pointer)) (foreign-alloc :pointer :initial-element (null-pointer))) ((foreign-alloc :pointer :initial-element (null-pointer)) (foreign-alloc :pointer :initial-element (null-pointer))) ((foreign-alloc :pointer :initial-element (null-pointer)) (foreign-alloc :pointer :initial-element (null-pointer))) ((foreign-alloc :pointer :initial-element (null-pointer)) (foreign-alloc :pointer :initial-element (null-pointer)))) '(:array :pointer 4 2))
