Compiling the following valid code snippet with "g++ -O" on the lno-branch
I get an ICE.

=================================
struct A
{
    int i[2];
};

void foo(A& a)
{
    for (int j=0; j<2; ++j)
        a.i[j]=0;
}
=================================

bug.cc: In function `void foo(A&)':
bug.cc:7: internal compiler error: tree check: expected integer_type or
enumeral_type or boolean_type or char_type or real_type, have reference_type in
number_of_iterations_cond, at tree-ssa-loop-niter.c:161
Please submit a full bug report, [etc.]

The ICE goes away if I pass the struct via a pointer.
