<p class="MsoNormal">Some more context.<br>
The t.rast.neighbors test seems to work with the current dev version<br>
"2048e1016" from 2021-05-19T09:38:49+00:00<br>
It fails however, with 7.8.5 from 2020-12-22T15:55:09+00:00 and an older development version "35edbf7dc"<br>
from 2020-06-03T16:03:52+00:00<br>
<br>
So, maybe one or more of the recent changes need backporting?<br>
