Description

Failure on pocl-cuda with `n=16` can be reproduced locally.
With intel-cpu it is not reproduced locally, and is intermittent on CI. See https://github.com/inducer/loopy/actions/runs/3787208816/jobs/6438795872

Oclgrind, NVIDIA, pocl-pthread all work.

Wonder if this is a test issue or a compiler issue.
