--- Comment #6 from Florian Weimer <fw at gcc dot gnu.org> --- (In reply to Markus Trippelsdorf from comment #5) > Ok. Well, I'm running GHC version 7.10.2, which is the latest. > (Not sure how to report this issue to the ghc folks). To be honest, if Richard thinks there is a GCC bug here (and I read comment #4 this way), he's likely right and I'm wrong.
