Hi, I finally found another OS X mountain lion install and can confirm the behaviour I described earlier: 32-bit: compiled code works, interpreted code works 64-bit: compiled code works, interpreted code fails Here's the test case: - cabal install gloss --flags"-GLUT GLFW" - cabal unpack gloss-examples - cd gloss-examples-1.7.6.2/picture/GameEvent - ghci -fno-ghci-sandbox Main.hs - main I get the following crash report: http://pastebin.com/jZjfFtm7 The weird thing is the following: When I run 'ghci' from inside 'gdb' (to find the origin for the segfault), everything works fine: ghci: segfault ghci from gdb: everything works I have no idea what's going on, so if anyone has any pointers on how to make sure ghci behaves the same in gdb please let me know.

The GLUT-backend calls system.exit when the window is closed, because 'exitMainLoop' is only defined within freeglut, which is not by default installed on non-linux platforms. There is hence no real point in running gloss applications with the GLUT-backend from GHCi.
I'll try to find a mountain lion install, and test if there's a difference between GLUT and GLFW

do these problems also happen if your'e using the glut backend? (because if its only glfw that has problems, then its something wrong in the ffi code, but if its both, that suggests there may be some sort of systematic problem?)
@Lyndon, that sounds like a bug... especially since scotty seems to have no C code in package... have you filed a bug report with the maintainers thats reproducible?
