This was in fact a genuine bug, which almost certainly appeared in 2.078 (Apr 2022). It is (I believe) fixed in the just-made dev-release of PDL, 2.085_01. Please try it and see if you agree.

Interestingly enough, this bug got reported independently by different people as a GitHub issue, on here, and on the mailing-list, in the last month or so, despite having existed for nearly 2 years.
