Stable work of validation tools should be always a priority, once these tools gave incorrect results, artists unlikely would use them again, in fear they might produce incorrect results in other places.
RC will be out soon, could you please fix this issue ASAP?

confirmed, the issue is different from #37583 by the way. It's very easy to test though.

Is there any chance of getting this issue fixed in 2.71 release?

I made the same request in blender/blender#35123, but it was closed as being a "To-Do":

From Campbell: "The intersection tests can be improved but when you move far the center point you start to loose precision (which is the cause of the problem). this is more of a todo then a bug, closing."
