I took a quick look at the problem and I made a patch replacing the panic with a sorry message proposing the usage of -fllvm. Here's what ghc says with my patch: {{{ ghc-stage2: sorry! (unimplemented feature or known bug) (GHC version 8.1.20160610 for x86_64-unknown-linux): Native code generator cannot produce code for Format.intFormat W128 Consider using the llvm backend with -fllvm }}} Is this solution convenient ? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10647#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
