--- Comment #1 from Gerhard Steinmetz <gerhard.steinmetz.fort...@t-online.de>

Detected with type "real" instead of "class(t)" :
$ cat z3.f90
program p
type t
integer :: n
end type
real :: g !!
abstract interface
subroutine h
end
end interface
procedure(h), pointer :: s
s => f
call s
s => g
call s
contains
subroutine f
print *, 'inside f'
end
subroutine g
print *, 'inside g'
end
end
$ gfortran-7-20161204 z3.f90
z3.f90:19:15:
z3.f90:5:12:
real :: g !!
2
z3.f90:19:15:
subroutine g
1
Error: Procedure 'g' at (1) has an explicit interface and must not have
attributes declared at (2)

Deleting that extra line gives a valid and correct program :
$ cat z0.f90
program p
type t
integer :: n
end type
abstract interface
subroutine h
end
end interface
procedure(h), pointer :: s
s => f
call s
s => g
call s
contains
subroutine f
print *, 'inside f'
end
subroutine g
print *, 'inside g'
end
end
$ gfortran-7-20161204 z0.f90
$ a.out
inside f
inside g
