After looking through all the replies here and seeing what you've tried so far, the only things I can think of are (a) something getting screwed up through an @EXPORT or (b) different DLL's getting mapped depending on the order of processing. Would it be possible for you to dump %INC at the end of the program run? It might be telling to trace through that and see what modules are included, then figure out which have DLL's. The answer might lie in the dependancy chains. Is there any way to trace module/DLL activation?
