Details

Now that #30 is fixed with 1146.78, we tried using SYCL_PI_LEVEL_ZERO_USE_NATIVE_USM_MEMCPY2D=1 with queue.ext_oneapi_memcpy2d. However, now that crashes with:

# /home/ubit/rpmbuild/BUILD/intel-compute-runtime-25.18.33578.77/shared/source/command_stream/linear_stream.h
# /home/bertoni/applications.hpc.argonne-national-lab.aurora.anl-testing/source/reproducers/dpcpp/sycl_native_memcpy_2d/bug_test.bats: line 19: 889529 Aborted                 (core dumped) SYCL_PI_LEVEL_ZERO_USE_NATIVE_USM_MEMCPY2D=1 ZE_AFFINI\

Is this a priority/blocking bug?
