Are you sure? I use ghc 7.6.2 (compiled with -O2) and without bang patterns for 1million iterations it blows stack space. With bang patterns it runs in constant space , same as other version?
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 :(
