Research direction
Start by reproducing the lesson 8, section 10 stencil example on Ubuntu 22.04 with GCC 9 and inspect the CudaAllocator construction error reported in stl_vector.h. Done means the example builds and runs without this constructor error, with the cause and required change documented in the issue.
