The C backend can currently (recent head) produce code with such patterns: /* Global Declarations */ /* Structure forward decls */ struct l_structtype_s; /* Typedefs */ typedef struct l_structtype_s l_fixarray_array3[3]; /* problematic declaration */ typedef struct l_structtype_s l_structtype_s; /* Structure contents */ struct l_structtype_s { int field0; }; gcc 4.0.1 will reject this with example.c:7: error: array type has incomplete element type this kind of code was accepted by previous versions of gc...

...none the less a somewhat serious one.
