Hi,
I shortly looked into this.
The problematic error seems to be the first omr of these (the rest is a result
of the first):
/build/reproducible-path/dune-geometry-2.11.0/dune/geometry/test/test-localfiniteelementgeometry.cc:

I think this should be valid c++ code, as the same construct is used outside of
the lambda without problems.
The code is
36: Dune::FieldMatrix<ctype,cdim,gt.dim()> A; // No error here
...
45: // mapping to generate coordinates from reference-element corners
46: auto f = [&](Dune::FieldVector<ctype,gt.dim()> const& x) { // error
because of gt.dim()
47: Dune::FieldVector<ctype,cdim> y;
48: A.mv(x,y);
49: y += b;
50: return y;
51: };
I'll do some further investigations, but for now I think this a compiler
problem.
Best,
Markus
