--- Comment #4 from janus at gcc dot gnu.org ---
Btw, I don't fully understand why "implicit none" should make any difference
here.
I can see that it would make a difference if you don't specify an interface in
the procedure statement:
module m
implicit none
contains
function f() result(z)
procedure(), pointer :: z
end
end module
But this version works fine, with and without "implicit none". In your original
test case the interface is fully specified, i.e. nothing is really 'implicit'.
I guess the actual problem is the self reference of the interface. We should
check if this is legal, and if not reject it.
