[Haskell-iPhone] Can anyone help me test GHC-iOS compiler?

Further investigation:

I grabbed 7.6.3 just to see if I somehow had a bad install of GHC, but the
problem still occurred.

The problem only occurs with LLVM 3.0.

It is not related to cross-compilation or Stephen's patches: I tested this
on multiple fresh clones with --with-gcc=clang.

LLVM 3.2, 3.3 and 3.4 do not exhibit the issue.

If anyone wants to try to reproduce, you can grab the LLVM 3.0 binaries
here Clang Binaries for MacOS
X/x86-64<http://llvm.org/releases/3.0/clang+llvm-3.0-x86_64-apple-darwin11.tar.gz>
and
just drop them in your path.

(Stephen, I'm now trying your patch with LLVM 3.2)

Cheers
Luke
