@JosephMouallem It looks like our changes in PR #74 cause this compilation error. Can you explain the behavior you were seeing when these variables were defined as allocatables instead of pointers?

#74 (comment)

[JosephMouallem]

Can you please keep these variables as pointers and instead remove the deallocate statement that is causing this compilation error?
