--- Comment #3 from Marco van Hulten <marco at hulten dot org> 2012-03-07 12:15:36 UTC --- This work-around of changing all entries to tracer(N:N) indeed works, in both the test case as for my original code where I found the problem. That is the NEMO 3.1 ocean model, with namelist_top containing 26 tracer entries of a larger structure, but similar to the test case.
