A simpler testcase:

[hjl@gnu-14 29921]$ cat bar.f90 
      SUBROUTINE foo(DPRS,FPK,LBOT,LTOP,KTS,KTE)
      IMPLICIT NONE
      INTEGER,INTENT(IN) :: KTS,KTE
      INTEGER,INTENT(OUT) :: LBOT,LTOP
      REAL,DIMENSION(KTS:KTE),INTENT(IN) :: DPRS,FPK
      REAL,DIMENSION(KTS:KTE) :: TREFK
      REAL :: PSUM, QOTSUM, SUMDP, TRFKL,DPKL,DST
      REAL :: FPTK, RDPSUM, RTBAR, DEN, DQREF
      INTEGER :: L
      SUMDP=0.
      DO L=LTOP,LBOT
        SUMDP=SUMDP+DPRS(L)
      ENDDO
      RDPSUM=1./SUMDP
      DO L=LTOP,LBOT
        TREFK(L)=TRFKL
      ENDDO
      PSUM  =0.
      QOTSUM=0.
      DST   =0.
      FPTK  =FPK(LTOP)
      DO L=LTOP,LBOT
        DPKL  =FPK(L)-FPTK
        PSUM  =DPKL *DPRS(L)+PSUM
      ENDDO
      PSUM  =PSUM*RDPSUM
      IF(-DEN/PSUM.LT.5.E-5)THEN
        LBOT=0
      ENDIF
      END SUBROUTINE foo
