[Bug c++/37554] New: [4.3/4.4 regression] ICE with invalid cast

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since GCC 4.3.0:

========================
struct A {};
class B : A {};

void foo(B b)
{
  (A)b;
}
========================

bug.cc: In function 'void foo(B)':
bug.cc:6: error: 'A' is an inaccessible base of 'B'
bug.cc:6: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in useless_type_conversion_p_1, at tree-ssa.c:1075
Please submit a full bug report, [etc.]
