$ cat z6.f90
subroutine s
associate (y => (s))
end associate
end
$ cat z7.f90
program p
associate (y => (p))
end associate
end
They are older (down to gcc-7), and produce different backtraces, e.g.
$ gfortran-6 -c z6.f90
z6.f90:2:14:
associate (y => (s))
1
Error: Expected association at (1)
z6.f90:3:6:
end associate
1
Error: Expecting END SUBROUTINE statement at (1)
$ gfortran-10-20191215 -c z6.f90
z6.f90:2:20:
2 | associate (y => (s))
| 1
Warning: Non-RECURSIVE procedure 's' at (1) is possibly calling itself
recursively. Declare it RECURSIVE or use '-frecursive'
