I have a function printErrors (as defined here http://dpwright.com/posts/2015/03/25/the-haskell-gl-package/#error-handling-utilities ) which I scatter around when things go wrong to try and find the root cause...

bug report! 

  m@(~(Just w)) <- createWindow 400 400 "Title" Nothing Nothing
  when (isNothing m) (error "Couldn't create window!")  

  GLFW.makeContextCurrent m

then no seg-faults.
