which compiler are you using to build?  Do you see the same thing
with a -O0 build?

This is a 2-stage build. stage1 compiler is gcc 4.8.2+r203692 on openSUSE
13.1. And stage1 is compiled with -O0. Second stage compiler is stage1
clang and C{XX}FLAGS is not modified.

I'll try second stage with -O0 now.
