--- Comment #5 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
The problem here is that check_case_bounds is getting NOP_EXPRs:
(const A) 0
introduced in convert_and_check called in c_add_case_label, and then it tries
tree_int_cst_compare on that, oops. STRIP_NOPS-ing case_low and case_high
would fix this...
