Reduced testcase:
      GO TO 50
   20       IF (IEXC.EQ.2)
     $         GO TO 80
   50      IF (IEXC.GT.0)
     $         GO TO 20
   80 K = K + 1
            IF( IEXC.EQ.0)
     $         GO TO 20
      DO 150 J = K, IEXC
  150    CONTINUE
      RETURN
      END

Here is a C testcase which makes this a dup of bug 17560:
void MAIN__ ()
{
  int k;
  int j;
  int iexc;
goto L50;
L20: if (iexc == 2) goto L80;
L50: if (iexc > 0) goto L20;
L80: k++;
if (iexc == 0) goto L20;
for(j=k;j<iexc;j++) ;
}
