--- Comment #2 from Andrew Macleod <amacleod at redhat dot com> ---
its just an incorrect type during the gori operand caclulation process. Just
got missed during the introduction of support for other range types.

testing underway now.

    Evaluate condition arguments with the correct type.

    Processing of a cond_expr requires that a range of the correct type for the
    operands of the cond_expr is passed in.
