[Bug fortran/32220] New: internal compiler error: in eliminate_temp_copies, at tree-predcom.c:1937

[dir at lanl dot gov]

While rebuilding one of my programs with the new version of gfortran, I hit
this error (This worked on an older version of gfortran)-

[dranta:~/tests] dir% gfortran -O3 -std=legacy -c ad78b.f
ad78b.f: In function 'derv':
