Configured and built with:
../gcc-4.2-20070221/configure --enable-languages=c --enable-bootstrap
--disable-nls && make BOOT_CFLAGS="-gstabs"
The result is:
[...]
Comparing stages 2 and 3
warning: ./cc1-checksum.o differs
Bootstrap comparison failure!
./dbxout.o differs
./insn-emit.o differs
./varasm.o differs
[...]
I recompiled these sources with stage 2 and stage 3 compilers into assembly,
for dbxout.c I got the following:
--- dbxout-stage2.s 2007-03-16 21:27:01.000000000 +0100
+++ dbxout-stage3.s 2007-03-16 21:29:42.000000000 +0100

The other files differ in the same manner. It's very similar to
