Which means it was probably "fixed" by

        * simplify-rtx.c (simplify_plus_minus): Remove final parameter.
        Always produce an output if we can remove NEGs or canonicalize
        (minus (minus ...)) expressions.  Provide a fast path for the
        two-operand case.
        (simplify_gen_binary): Do not call simplify_plus_minus.
        (simplify_binary_operation_1): Reassociate at the end of the
        function.

or more like worked around.
