While trying to boot linux 2.6.34 built with gcc from latest gcc-4_5-branch the
kernel would not boot. Same kernel would work fine with gcc 4.4.4 Reducing to
individual optimization phases. So far I have seen that when compiled with -O2
the kernel crashes however when I change the flags to -O2 -fno-ipa-sra then
it works well.
I don't have a small test-case as of now. I am trying to reduce it but it might
take some time. Meanwhile I wanted to open the bug so that if someone else
has information on similar issue can chime in.
