[Bug c++/34911] New: [4.1/4.2/4.3 regression] ICE with vectors of bool

[reichelt at gcc dot gnu dot org]

The following code snippet triggers an ICE since GCC 4.0.2:

============================================
bool foo() __attribute((vector_size(8)));

void bar()
{
  foo() & foo();
}
============================================

bug.cc: In function 'void bar()':
bug.cc:5: internal compiler error: in same_scalar_type_ignoring_signedness, at
c-common.c:7203
Please submit a full bug report, [etc.]

I'm not sure whether the code is valid or not, GCC 3.4.[56] accepted it,
but GCC 4.0.[01] rejected it.
