[cffi-devel] MEM-REF and BARE-STRUCT-TYPE-P issue

[CRLF0710]

Hi all.

#1 In src/types.lisp there is following code in function MEM-REF:
....
    (if (aggregatep parsed-type)
        (if (bare-struct-type-p parsed-type)
....
and its compiler macro has similiar code.
However, the gf bare-struct-type-p has no method for  foreign-array-type
whose objects will obviously pass the aggregatep test. So it breaks some
code (on ccl).
I suggest that case be added as a method too?(What should it (and even more
user-defined types) return?) Or should the checking code be modified here?
(As i understood, the whole bare struct mechanism is for compatibility...)

#2 And another thing, i've realized that in my last modification to the
STRUCTURE-BY-VALUE-P function (the modification is already pushed to the
repo) i should have tested to see if it is a bare struct type. Without the
check it will put some deprecated style code into using libffi, which also
works correctly but involves unnecessary libffi dependency. Should I fix
that?

Regards,
Charles Lew
