[Bug c/28136] New: [4.0/4.1/4.2 regression] ICE with incomplete array type

[reichelt at gcc dot gnu dot org]

The C frontend crashes on the following line of invalid code since GCC 4.0.0:

================================
int i = (struct A[]) {};
================================

bug.c:1: error: array type has incomplete element type
bug.c:1: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in c_parser_postfix_expression_after_paren_type, at
c-parser.c:5432
Please submit a full bug report, [etc.]

Before the code was wrongly accepted.

I'll post a patch soon.
