Hi
I'm using GHC 6.10.1 on OS X. Any ideas on what may be going on?
Wow. Awesome bug! Got lots of discussion at Galois :)
I can confirm a difference in running time, we also tested with 6.8.x and 6.10, with similar results.
Is -O2 implying -fvia-C? If so, could it be the evil mangler? Is there a non-alpha rename difference in the Core? Very cool bug :-) Thanks Neil
