The following invalid code snippet triggers an ICE since GCC 4.1.0:
template<intstruct A
{
static const int i;
};
template<int Nstruct B
{
char c[A<N>::i], d;
};
B<0b;
bug.cc: In instantiation of 'B<0>':
bug.cc:11: instantiated from here
bug.cc:7: internal compiler error: tree check: expected integer_cst, have
nop_expr in walk_subobject_offsets, at cp/class.c:3126
Please submit a full bug report, [etc.]
