Re: Do different compilers produce different .mod files?

Such incompatibilities usually imply to me less than ideal design of
the .mod file structure.

Yes, but in a different sense. The one example I clearly remember was going from CVF 6.0 to CVF 6.5: I believe it was because the compiler guys found that the data structures they were using - whether in-memory or in-file - were not up to the job, as the many bugs and massive performance problems in (nested) USE handling showed. So they bit the bullet and re-designed those data structures, and with it the .mod file format, from scratch.
