with-foreign-object will always give you a pointer to what has just
been allocated. In some cases your test code is allocating enough
memory to hold a pointer, other times it's allocating enough memory to
hold a struct, but you always get a pointer to that allocated memory.
And since CFFI pointers are untyped, the type you specify when
dereferencing them is crucial.
