Dear SevenThunders (if that is how you like to addressed)
Thanks for extracting a small program that exhibits the leak; that is
really helpful. We'll look into it. Would you like to create a Trac bug
and attach your files?

You can call me
I'm not sure if this is a bug, but it sure seems that way to me. When using
the wrapper technique for creating a Haskell callback function it seems
that freeHaskellFunPtr is not properly freeing the resource.
Here is an example program

I just tried it under GHC 6.6 with the same results. If the DLL is loaded it
crashes when it's

Here is the promised simple example. This example will cause an exception
when the DLL is unloaded
