[LLVMdev] Problem with MemoryDependenceAnalysis

[Amr Yehia]

no .. i am calling a function pass from a module pass, adding other 
function passes to my module pass works, but when i try to add 
MemoryDependenceAnalysis it gives error

I want to report a bug but i don't know if this is a real bug or i am 
doing something wrong, knowing that i am adding other function passe to 
my module pass and it works fine.

the error i get:
