This has occured to me when trying out the cluster_parallization branch with alpaka's SYCL backend. SYCL complains that alpakaCopy() tries to copy overlapping memory regions. In this case, the src and dst pointers are identical, causing the program to crash with the mentioned error.
This error occurs at multiple locations in the Dispenser code and can be solved by guarding these copies with if(dev->id != previousDev).
