[jhc] possible bug

23 Sep 2010

      Hello!

I've played with jhc and sdl binding a bit on osx.
Unfortunately it does not worked. The original example compiled, but exited
with exception. (it said the there is no autoreleasepool defined...)
After a little modification I've got correct haskell code, what fails with
gcc.

I've attached the source file.
Cheers,
Csaba
