[Bug c++/31780] New: [4.3 regression] ICE with incompatible types for ?:

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following invalid code snippet triggers an ICE on mainline:

===========================================
bool foo();

void bar()
{
  __builtin_expect(foo(), 1) ? 0i : 0;
}
===========================================

bug.cc: In function 'void bar()':
bug.cc:5: error: could not convert '0' to 'int __complex__'
bug.cc:5: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in tree_ssa_useless_type_conversion_1, at
tree-ssa.c:900
Please submit a full bug report, [etc.]
