[MITgcm-support] diagnostic errors

[Patrick Heimbach]

Hi Matt,

what you're seeing is very likely 
particular to the use of diagnostics in 
conjunction with the adjoint.

Because some of the code gets replaced by
TAF-generated code, there might be code missing
that's not required to compute the cost function.
Usually I take care of this by updating corresponding
flow directives, but things in pkg/diagnostics have
been changing so frequently that it was/is impossible
to keep up.

I'll try to sort this out this week.

Cheers
-Patrick
