By redirecting the build system's use of `nm` to use `nm-classic` the segfault does not occur. I'm not sure what goes wrong with `llvm-nm` but it would be great if the build could be fixed to be able to use it without segfaulting, since using `nm-classic` is a hack and Apple may retire it at some point. https://github.com/Homebrew/homebrew-core/issues/371 https://github.com/Homebrew/homebrew-core/pull/449 https://gist.githubusercontent.com/ilovezfs/dd26686da7e545fabca1a517e3adb039... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11951 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
