--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The warning is issued because we inline sub.
As we do not know whether 'o' is used we don't issue a warning in sub() that
o is not initialized (does intent(out) mean it comes in uninitialized?).
Just looking at the program sub has intent(out) q and thus we can reasonably
expect it to be initialized.
So - is 'o' uninitialized in
subroutine test(o)
integer, intent(out) :: o
print *, o
end subroutine
? It doesn't seem so (we don't warn but I also think we have no way to
annotate sth as uninitalized that is passed by reference).
