I think this could be because of gcc bug
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48190
that bug has now been fixed and backported to gcc-4.5 and gcc 4.6
branches as well
however this fix has to go into the gcc in distro that you are running
on build host
we will get this fix into oe-core gcc as well but that may not help
with qemu-native
