I am now seeing the same thing with e.g. Raw-SHA256-ng in an OpenCL
build. Somehow it allocates 60+ MB on the NVIDIA GPU in bull. %-)
magnum - I think there's a bug somewhere in bleeding, where OpenCL
builds make some use of GPU even in formats that are not GPU-enabled.
Weird. Can you look into this, please?
