The test case starts passing on mainline with this patch:

        * fold-const.c (int_const_binop): Return NULL_TREE when an expression
        can't be evaluated at compile-time (instead of calling abort).
        Return NULL_TREE for division (and modulus) by zero.
        (const_binop):  Return NULL_TREE for floating point operators that
        aren't handled by real_arithmetic.
        (fold_binary):  Eliminate "wins" variable, and "binary" label, by
        folding operators with constant operands early.  Assert that
        operands are non-NULL.
