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

[redriver at korea dot ac dot kr]

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 .

What version of GCC are you starting with?
This works for me on an i686-linux-gnu machine (a pentium 4D).

I think I found the problem. Previously, I use the gcc-3.2.2 to bootstrap the
gcc-4.2.0. But when I used higher version of gcc (gcc-4.1.2) to bootstrap then
there was no error. I think there is some incompatible between the two versions
3.2.2 and 4.2.0.

This issue has already been worked around in 4.3 (and IIRC 4.2.1.) so closing
as fixed.
