OMEGA in Datmodyn not defined consistently with rest of model. Causes SCM failure in DEBUG build.

When trying to debug another problem with the SCM and the develop branch of MAPL I hit another problem, that's not a MAPL issue at all, MAPL just caught it. I suspect it has been there all along as no one every probably runs a debug build of the model when running the SCM.
Here is what I'm seeing when running:

forrtl: severe (408): fort: (33): Shape mismatch: The extent of dimension 3 of array PTR3 is 72 and the corresponding extent of array PTR30 is 73

I put a few prints in and this a coupler in AGCM, it's trying to couple a variable named OMEGA, seems to be coming from DYN over to Physics.

The issue is that in the initialize method, the coupler variable where the accumulation is stored is made with a pointer obtained from OMEGA that is clearly "edge" in that is goes from 0 to 72, but later in the run, the actual variable pulled from the state that is going to be averaged is 1 to 72 and center so you get the shape mismatch.

The problem is everywhere in the model in FV3, Physics OMEGA is MAPL_VLocationCenter, but in GEOS_DatmoDynGridComp.F90, it is MAPL_VLocationEdge. That's it, so I guess DatmoDyn is wrong.

Another question could be why is omega and only omega being coupled with the generic coupler...

To run the case:
Build GEOSgcm (use the DEBUG build!) and then go to install/bin and run scm_setup like:

./scm_setup --expdir /path/to/directory/arm_97jul --case arm_97jul --account s1873

Obviously, change the account to whatever you like. Then go to /path/to/directory/arm_97jul and in there you can just run:

./scm_run.j |& tee log.run

By default arm_97jul runs for 30 days, but you can change CAP.rc to be 1 week or whatever. Even 30 days runs quick.

After consulting with @atrayano this is a bug, you can't couple things that have different dimensions in the specs...
