[Bug c/27718] New: [4.0/4.1/4.2 regression] ICE with sizeof of incomplete type

[reichelt at gcc dot gnu dot org]

The following code snippet triggers an ICE in the C frontend since GCC 4.0.0:

=================================
int i = sizeof(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_expr_sizeof_type, at c-typeck.c:2156
Please submit a full bug report, [etc.]

Testing a patch.
