[Bug fortran/37779] Missing RECURSIVE not detected

[burnus at gcc dot gnu dot org]

------- Comment #2 from burnus at gcc dot gnu dot org  2008-11-22 19:03 -------
Another code which is not rejected. If the parent procedure is called by a
contained procedure there must be a recursion:

subroutine test()
  call sub()
contains
  subroutine sub()
    call test()
  end subroutine sub
end subroutine test

NAG f95 detects this:

Error: hfjf.f90, line 7: Invalid recursive self-reference to TEST

as does openf95:

openf95-343 openf95: ERROR SUB, File = hfjf.f90, Line = 5, Column = 10
  A RECURSIVE keyword must be declared for a subprogram so that the subprogram
can be called recursively.

ifort, g95 and gfortran accept this program. (Can be also moved into a
different PR.)
