Simon Peyton Jones have recently commented on #11665 (attoparsec one) 
and it looks like he has it well under control. Of course I would be 
glad to try reproducing that again if needed.

Talking about #11664 I think it's worth knowing that GHC 7.10.3 has some 
hard time compiling recent Warp, but the good point is that (supposedly) 
GHC 8.0 doesn't have this problem anymore, so the ticket could be 
relatively safely closed.
