I don't see that behaviour here: 

Prelude> 3492928512*3492928512
12200549589942534144

and this is the machine that built the x86_64 6.6.1 binary bundle, it should be exactly the same compiler.

Possibly a GMP problem?

I can't reproduce this either.

Where did your GHC come from? The bindist? A Linux distribution package? Compiled yourself?

Do you know if any mk/build.mk was used?
