This is on GHC HEAD. However this was not so "standard" testing here, as 
this was a build which used Ubuntu's provided preliminary LLVM 3.0 
packages. I did this in order to test them. So now, I'm back to my own 
LLVM 3.0 build and building the same GHC tree with this to see if this 
is the problem caused by interaction with either Ubuntu's LLVM 3.0 
packages, or new Ubuntu 11.10 or this is really a bug in HEAD. My bet is 
on Ubuntu's LLVM 3.0 packages as I guess they built them with GCC and 
default optimization which is not that good[1].

Anyway, new build is just finishing and full testing takes about 24 
hours on this board so I'll send you result during Wednesday probably...

Thanks,
Karel
