I agree that it would have been better for image_distinct to be optional. I

Jakub, Indeed I saw them, but is there any explanation (except "UB") why it
does copy by 16 if the memory overlaps?

Third thought. Here are the programs you meant to write (without error

The example that you give shows that setting the undefined part to zero

On 2nd thought.
Of course, the results are different.
In your first example, you have
call random_init(repeatable=.true., image_distinct=.true.)
which gets you processor-dependent seeds. In

There is no --as-needed support.
I think either approach would simplify things as most targets don't need to
