I just tried to bootstrap gcc 4.5 mainline snapshot 20090730
and it failed when comparing stage 2 and stage3.
There is the output
Comparing stages 2 and 3
warning: gcc/cc1-checksum.o differs
warning: gcc/cc1plus-checksum.o differs
Bootstrap comparison failure!

configure line was
../src/gcc-4.5-20090730/configure --enable-languages=c,c++
--prefix=/home/dcb/gcc/20090730/results --enable-checking
--enable-build-with-cxx
The previous snapshot 20090723 also failed to bootstrap
but the one before that 20090716 bootstrapped fine.
I suspect a code change somewhere between 20090716 and 20090723.
