--- Comment #3 from Tobias Burnus <burnus at gcc dot gnu.org> 2010-10-02 11:33:43 UTC ---
Summary as far I understand it. Cf.
http://j3-fortran.org/pipermail/j3/2010-September/003852.html :

module m
  procedure(), pointer :: p, p2
  protected :: p
end module m

subroutine two
  use m
  procedure(), pointer :: ptr2
  ptr2 => p  ! Invalid
end subroutine two

It is invalid as "p" is PROTECTED, but gfortran does not diagnose this. That's
something the variable-definition patch misses.

 * * *

subroutine one
  use m
  procedure(), pointer :: ptr1 => p2
end subroutine one

That's invalid as "p2" is a pointer, cf. PR 45290.
