I passed over the ticket. Now, I know that this is a bug, but has not fixed yet. There are (or ware ?) problems about performance and integrity for handling exceptions. It seems that a narrow range of use-cases cause the stalling. Someday we have a type-focused VERY NICE library, (I hope that) it will be resolved.
