Yes, it all make sense from that angle. On the other hand, I want to be focus on kernel rather than compilers by using a stable and rocket-solid version. Not mentioned the time lost by compiling and properly manage my own toolchain in an automated environment, using such new version of compilers means that I have to inevitably deal with compiler bugs occasionally. Anyway, it is just some other more bugs I have to deal with, and I don’t have a better solution to offer right now.
