Sure, I will file a ticket once I have more clarity on the problem. BTW, I
forgot to mention that this is with ghc-7.10.3. I will try to see how
things stand with 8.0.1 at the assembly level though I have not seen any
difference in the benchmark performance. I guess it is better to work off
8.0.1 anyway since things might have changed significantly.
