X shall be an interoperable data entity that is not an assumed-size array." It might be sufficient to test -- besides the obvious stuff (cf. SIZEOF) -- just for derived types that those are BIND(C). * * * By the way, I think one should reject proc-pointers for both SIZEOF and C_SIZEOF. For C_SIZEOF because they are not interoperable (only type(c_funptr) is) and for SIZEOF as the pointee size and not the pointer size is returned, which does not make sense for functions. (gfortran currently returns 1 byte.)
