Hi,

FYI, my testrobot caught some errors when this patch is applied.
(BTW, gcc builds fine)

I am not seeing the above errors when I build with the following commands:

make config T=x86_64-native-linuxapp-clang
make install T=x86_64-native-linuxapp-clang -j

Are you using a different clang config file?

Bernard.
