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.]
