What about debuggers? For Fortran there are some powerful commercial debuggers available, incl. Parallel debugging and even reverse debugging (being able to step backwards based on snapshots).
I tend not to use debuggers very much myself so not speaking on a ton of expertise, but I think it's probably safe to say the Fortran ones are going to be a lot better on that front. There are a few options for debuggers so far, but no parallel ones that I know of yet.
