[Bug bootstrap/32334] New: Bootstrap comparison failure when comparing stage 2 and 3

["redriver at korea dot ac dot kr" <gcc-bugzilla at gcc dot gnu dot org>]

I installed the gcc-4.2.0 on Intel(R) Xeon(TM) in a clean directory which is
different from the source one with the following configuration: 
../gcc-4.2.0/configure --prefix=$prefix --enable-language=c,c++ --with-gnu-as
--with-gnu-ld

And then I got the following error: 

Comparing stages 2 and 3
warning: ./cc1-checksum.o differs
warning: ./cc1plus-checksum.o differs
warning: ./cc1obj-checksum.o differs
Bootstrap comparison failure!
./cfg.o differs
./cfgloopanal.o differs
./loop-iv.o differs
./predict.o differs
./profile.o differs
./value-prof.o differs
./ipa-inline.o differs
make[2]: *** [compare] Error 1

make[1]: *** [stage3-bubble] Error 2
make[1]: Leaving directory `/home/compiler/redriver/project3/gcc/gcc-install'
make: *** [all] Error 2

Could you please tell me what problem with it? What does the bootstrap
comparison mean? Whether any of my prerequisite tool/packet didn't fit with
GCC-4.2.0. Because I installed the gcc-4.1.2 version in the same machine, with
the same configuration but it was ok. Thanks very much .
