I consider that a bug. Soon, every format will get a done() in bleeding-jumbo and then we can review these things. And after that, finally, we'll be able to use --test for GPU builds and include all GPU formats.

Thanks, committed now. I will start making use of that macro right away, I recently added some callocs in Dhiru's pbkdf2 formats.
