Another clue.  I'm seeing the same bug in gfortran-13, except that I have to
use  -O0 for both cases of mc11ad.f90 in or out of the contains statement.

Similarly, if I put the set of va09ad.f90 routines in a module, I have to use
-O0 to get correct answers.  -O3 causes a bug with va09ad.f90 in a module as
well.
