Comment:
I think we'll need more information here. Can you construct a small
example of a `ForeignPtr` that is freed when you expect it to be retained?
Since a `ForeignPtr` can only be derferenced in the `IO` monad, is `v` in
your example an `IO` computation? Or perhaps you're using
`unsafePerformIO` to dereference the `ForeignPtr`?
