I've just asked a colleague of mine about this and according to him  
it's perfectly legal in Windows to have multiple relocation blocks for  
the same section, in which case Windows will also fixup everything  
twice. So simply ignoring such relocations is normally wrong. Which  
dll from which game is this?
