Ok.
It's good I didn't actually close this bug report as I wanted to - I thought
about sending the email to nnn-done at bugs.d.o, but forgot about this -done part.
(I was dealing with old bugs, there are *lots* of them reported against samba
package, they're just sitting there for years without any action or attention,
so something has to be done with them anyway).

I for one don't know what vfs_fruit *is*, to begin with. Just read briefly the
manpage, -- well, it has quite some things, it seems, most of which is related
to MacOS. I don't have a MacOS machine.
So basically, I know nothing about how to verify this.
And the thing is that I can't really do anything there.
It's best to be handled upstream anyway, I don't know
samba internals. I can handle packaging issues, but
for the real code issues, especially the ones which I
can't even verify myself - I can only close the bug
reports so the reports wont stack and hide somethin
which I really can fix.
Can we at least retitle this as "... on 32bi platforms",
since what you describe suggest that it's not specific
to 32bits.

Umm. So we've hit some internal limitations with off_t size
here. That's understandable. Just yesterday we talked with
Qemu folks - they just *detest* 32bit platforms, since it's
extremly difficult to map even the 32bit address space into
its own 32bit address space, they have to perform all kinds
of tricks which doesn't work anyway in the end, - it is just
can not be done.

I see. Well, this is at least practical, I think.
Thank you very much for your input!
