I am thinking this is a fortran front-end bug:
reduced testcase:
      COMMON /SUBSTR/ NPHASE,NSUB
      END
      SUBROUTINE ZIPP
      COMMON /SUBSTR/ NPHASE,NSUB,IDUM1,KURPA,KTBUF
      IF (NSUB.LT.0) THEN
        KTBUF=KTBUF-1
      END IF
      END

I think we get the wrong type for the common section, SUBSTR.
