There seems to be a fix for this for ghc-7.8 (commit db9b63105a54),
which we can try test and backport.
Comment 1 Jens Petersen 2013-06-25 10:02:18 UTC 
Hopefully fixed in ghc-7.4.2-11.1.fc19.

That's the good news - the bad news is I don't think
this will build on ARM without rebootstrapping ghc probably. :-(

I assume there is a good reason for shipping llvm-3.3-rc in f19-final...

Mesa 3.2 requirement for newer graphics card and feature support like video offload. There was a heads up mail send to devel quite some time ago
