That's because you don't _have_ a dbuf. The palemu target doesn't
support DirectBuffers...
You probably forgot to check your return codes somewhere.

What compiler is that? Sounds like a broken compiler to me.
dbuf->resource is a pointer, and the fact that dbuf is a const *
shouldn't affect the type of dbuf->resource afaik.
