This program should generate an error; it's illogical. If the alignment
of the element is greater than the element size, then arrays of such a
type should be disallowed. Otherwise, stuff in either the compiler or
the program itself could make the justified assumption that things of

The gcc.dg/compat/struct-layout problems seem to stem from
struct-layout-1_generate.c. In generate_fields() it generates random
types, some of these are arrays of some base type. Then based on
another random number we might add an attribute like alignment. There
is no check to ensure
