Comment:

 Replying to [comment:7 rdragon]:
 > It looks like this issue has been fixed in GHC 7.10.2 or before. I can
 reproduce the problem with GHC 7.8.3, but not with 7.10.2. In both cases I
 use the 64-bit version.

 Since bisecting pre-7.10 commit ranges is rather difficult, I say we leave
 it at this. Let's hope it's really fixed! If someone really wants to
 investigate further, they can of course do so, and reopen this ticket.
