Does anyone know what causes these? This used to work, like, a month ago. It builds fine without the -fhpc.

What has changed in that time? New Ghc? New updates from your OS? New code in your project? Because it builds fine without -fhpc it sounds like a ghc bug.

What version of ghc and on what OS? Is this 64 bit or 32bit?

Basically, I think we need more information to be helpful.

Gentoo, amd64. Happens on at least two different machines. There have been plenty of code changes since it worked last, but no OS/GHC updates.
