Hello, I'm using ghc 7.10.1 to compile OpenGLRaw which is now impossible with -O1 and -O2 due to "ghc : out of memory error" on a 4GB linux host. The file making memory explode is Graphics.Rendering.OpenGL.Raw.Functions <https://hackage.haskell.org/package/OpenGLRaw-2.4.1.0/docs/src/Graphics-Rendering-OpenGL-Raw-Functions.html>. With -O0 it uses 600 MB.
The file is really huge, but I could compile it with prior versions of ghc.
