--- Comment #32 from Kazumoto Kojima <kkojima at gcc dot gnu.org> ---
(In reply to John Paul Adrian Glaubitz from comment #28)
I should have been more clear about these comparison messages.
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.
