Thanks for this report. I will investigate.

I reproduced the issue. Looks like a bug all right. Debugging.
from yask.
The issue turned out to be unexpected expressions ("t + 0" for example) in the stencil indices. These should now be recognized (as equivalent to "t" in the example) and handled properly. I pushed a change to the "develop" branch if you want to test it before I merge it into "master", probably sometime tomorrow assuming all regression tests pass. Performance of the test case you provided increased 1.86x on my system, consistent with your measurement.

The "t+0" occurs as the stencil itself is produced using a different tool. Thank you for the hotfix, it works.
