[CUDA] Wrong sycl::item value for prime number sycl::range

[tdavidcl]

Hi,

I just found a bug in dpc++ (intel/llvm git commit : b95b2d8). 

queue.submit([&](sycl::handler &cgh) {

    cgh.parallel_for(sycl::range<1>{86413},[=](sycl::item<1> item){
        if (item.get_linear_id() >= 86413) {
            sycl::ext::oneapi::experimental::printf(" 86413 error\n");
        }
    });


}).wait();

 This snippet execute the printf statement, it seems to be related to prime number sizes (86413 is a prime).

This can be worked around by switching to a nd_range ...

Compiler flags : -fsycl -fsycl-targets=nvptx64-nvidia-cuda

Any idea why this is the case ?

Thanks,
