The compiler was crashing due to an incorrect assumption about the availability of lower/upper bounds for undefined ranges. The operator_not_equal::fold_range function now calls empty_range_varying to handle these cases, preventing the ICE. This issue was introduced in r14-4153 and this commit reverts to the prior behavior.
