I have begun to look into the reported warnings. Most are harmless and
can be corrected very easily. Some point to cases where an error check
in the code is missing. Other are difficult to avoid, e.g. when
"const" or "restrict" is involved.

And in one case I found an actual error in RotatingSymmetry90. Tensor
indices where calculated in the wrong way. This concerns "dd" tensors,
i.e. 3x3 tensors without symmetry. I believe we don't use these, so
the error went undetected.
