In going back with the previous runs that I've done on power10, it worked with sources checked out on October 17th, but failed with sources checked out on November 4th and November 17th. I used the options: -g -mlittle -save-temps=obj -ffast-math -Ofast -mcpu=power10 -mrecip \ -funroll-loops -m64 -finline-arg-packing -static-libgfortran \ -fstack-arrays -std=legacy -frandom-seed=spec2017
