Since r10-6527 fold_for_warn calls maybe_constant_value, which means it can fold more than it previously could. In this testcase it means that cp_build_binary_op/RSHIFT_EXPR set short_shift because now we were able to fold op1 to an INTEGER_CST. But then when actually performing the shortening we crashed because cp_fold_rvalue wasn't able to fold as much as f_f_w and so tree_int_cst_sgn crashed on a NOP_EXPR. Therefore the calls should probably match. PR c++/94955 * typeck.c (cp_build_binary_op): Use fold_for_warn instead of cp_fold_rvalue. * g++.dg/cpp0x/constexpr-shift2.C: New test.
