The following fortran subprogram: 

      SUBROUTINE USELESS (STRING)
      CHARACTER*(*) STRING
C-----------------------vvvvvvvvvvv
      CALL BART (STRING, LEN(STRING))
C-----------------------^^^^^^^^^^^
      RETURN
      END

elicits the following message:

uopt: Warning: harmless compiler bug detected (LDA length 0); please report to MIPS

when compiled with optimization levels 2 (and above).
O/S:	IRIX 3.3.1
Compiler: f77 -V shows "Mips Computer Systems 2.0"

But Hey, Don't have a cow man!  It's Harmless!

P.S.: Consider yourselves informed!
