------------------------+---------------------------------------------------
I'm experiencing spurious behaviour (segfaults sometimes) using GHCi when
working with code that interacts with C-libraries. It seems to be an OS X
only bug.
The spurious behaviour is as follows:[[BR]][[BR]]
OS X 10.8 (gcc 4.2.1, clang 4.0):[[BR]]
- 32-bit: interpreted and compiled work correctly[[BR]]
- 64-bit: only compiled code works correctly, interpreted code segfaults
(11)
OS X 10.6 (gcc 4.2.1, XCode 3.2.6):[[BR]]
- 32-bit: interpreted and compiled code work correctly[[BR]]
- 64-bit: interpreted and compiled code work correctly
Additionally (OS X 10.8):
When I run 'ghci' from inside 'gdb' (to find the origin for the segfault),
everything works fine (e.g. _no_ segfault).
Here is a link to the crash report given by OS X:

And this is the test case:
{{{
cabal install gloss --flags"-GLUT GLFW"
cabal unpack gloss-examples
cd <unpacked-dir>/picture/GameEvent
ghci -fno-ghci-sandbox Main.hs
main
}}}
I'm filing this bug report in relation to the following thread on haskell-
cafe, which is about removing the 32-bit recommendation for Haskell
