Summary

in vector-space division of FieldVector
by scalar
Ouch! Would you mind adding a test that finds this?
I'm sorry, but I do not have time currently to write the test. But it is a fundamental bug and it results in a fail of all tests of my derived project. So, I would suggest to merge this bugfix soon and to put the test implementation on a TODO list for dune-2.7
