Comment (by Fuuzetsu):

 I certainly plan to investigate each of the cases mentioned in the
 description but if you have any specific source files you know are likely
 to change between compilation, I ask that you post them here: I spent
 quite a lot of time trying to come up with some while I'd rather be fixing
 the problem instead.
