I will merge the original c code into the spreadcoin fork. the gpu finds a solution, it will be verified by the cpu. The current build have no verification done by the cpu.
I'm confused. You said you found a bug in the hash? Or are you considering the lack of verification to be a bug? I left it out kinda intentionally since submitting "bad" solutions doesn't really hurt and I just didn't bother with the CPU verification. But yea it would be nice and very helpful in debugging. Running in benchmark mode with a low target would be a good tool for checking if the GPU hashing works or not, instead of having to wait until you actually solve a block.
