It's likely. How much drift between the two revisions? Can you recreate the ICE if you write and read with the exact same revision? If so, please file a bug.

Please add version checking. gfortran's module files (extension .mod) that are generated from source files that contain MODULE ... END MODULE constructs *now* contain version information.

I still get occasionally beaten by picking up modules from 4.3 that don't have this - you'll get all sorts of unintelligible error messages that just distract from what's really wrong.
