Warning is warning and doesn't cause failure. gcc/cc1*-checksum.o objects depend on the virtual addresses of executables. If randomize-va-space feature of kernel on the target machine is used, then stage2/3 cc1*-checksum.o differs without any compiler problem. These differences are warned but aren't handled as errors for that reason. It looks that the log for 4.8.4-2 includes gcc/d/ctfeexpr.dmd.o differs line just after its 'Bootstrap comparison failure!' line. It looks that that is the cause of failure and is a differnt issue. For the original PR, I've apply the fix on 5/6 in behalf of Oleg after the regtest on trunk which has become possible because 66181 is fixed.
