[Bug fortran/32150] New: Strangeness when repeating an INTERFACE entity in ONLY clause of USE statement

[enok at lysator dot liu dot se]

I have a MODULE containing an INTERFACE . I then USE this interface name in
another file, but accidently specifies the namd twice after the ONLY clause.
This generates strange error messages. It's hard to say exactly what triggers
the error - it seems that it only happens for INTERFACE names.

Other compilers I tried silently accepts such code (maybe a warning would be
the optimal response).


MODULE MOD
  IMPLICIT NONE
  INTERFACE FOO
    MODULE PROCEDURE A
  END INTERFACE
CONTAINS
  SUBROUTINE A
  END SUBROUTINE A
END MODULE MOD

PROGRAM TST
  USE MOD, ONLY : FOO,FOO
  IMPLICIT NONE
END PROGRAM TST
