[Bug fortran/31211] New: wrong code generated with gfortran

["jv244 at cam dot ac dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

With a recent gfortran, the following compiles, but generates the wrong
results:

MODULE T
  INTERFACE cp_log
     MODULE PROCEDURE cp_logger_log
  END INTERFACE

  TYPE cp_logger_type
    INTEGER :: a
  END TYPE cp_logger_type

  PUBLIC :: cp_log, cp_logger_type

CONTAINS

  SUBROUTINE cp_logger_log(logger)
    TYPE(cp_logger_type), POINTER ::logger
  END SUBROUTINE

  FUNCTION cp_get_default_logger() RESULT(res)
    TYPE(cp_logger_type), POINTER ::res
    NULLIFY(RES)
  END FUNCTION cp_get_default_logger

END MODULE T

USE T
 CALL cp_log(cp_get_default_logger())
END
