Why do you expect the .mod files be the same with or without a print statement?
IMO if two files differ in contents, it is likely they also differ in size.
AFAICT compiling several time the attached test does not regenerate the
test_mod.mod file unless I do some modification in the module. So you probably
need a more complex test to expose the behavior you are complaining about.

You can always give the IMPURE attribute to the routines, but I have no idea if
it helps.
