I opened a ticket a few days ago already https://ghc.haskell.org/trac/ghc/ticket/8991 but no answer. I guess it's difficult to reproduce.
In fact if I recompile HSE using your same PKGBUILD, it works fine! I'm using llvm-3.4-1 and glibc-2.19-3. I wonder what could be different between your build environment and mine. Very strange!
