WebCLKernel.setArg(..., Float64Array([c])) fails for kernels with scalar double arguments. This seems to be specific to double type: other scalars seem to work well. Reproducer:

            var context = webcl.createContext(device);
            var program = context.createProgram(source);
            program.build([device]);
            var kernel = program.createKernel("init");
            var buffer = context.createBuffer(webcl.MEM_READ_WRITE, 1024*8);
            kernel.setArg(0, buffer);
            kernel.setArg(1, new Float64Array([0.0])); /* Uncaught OpenCL exception: Unknown */
