[Bug fortran/23177] New: internal compiler error with -O option

[dir at lanl dot gov]

When I try to use the -O option, I get a internal compiler error -


[dranta:~/tests/gfortran-D] dir% gfortran -O -c s5main.f
s5main.f: In function 'mtlsc':

Confirmed:
IV-OPTs is causing it:
  #   VUSE <bk65>;
  D.545_65 = MEM[symbol: bk65, index: D.685_81, step: 4B, offset: -4B];

Notice how the VUSE operand was not renamed.
