Okay, I have found the root of allocation problem. It is not because of 
7.4.2. If I use -auto-all it somehow change code generation and start 
allocating. If I remove -auto-all from command line than no allocation 
occurs. That really weird because now I don't know how to profile and 
get meaningful results :(
