[Bug c/35748] New: ICE with cast to invalid union

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since at least GCC 2.95.3:

=================================
union U { void x[1]; };

void foo()
{
  (union U)0;
}
=================================

bug.c:1: error: declaration of 'x' as array of voids
bug.c: In function 'foo':
bug.c:5: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in build_c_cast, at c-typeck.c:3631
Please submit a full bug report, [etc.]
