Like we did for previous gcc versions, we only want to support one minor version at a time for a given major branch. So at the gcc 4 era, it meant we would only package one gcc 4.8, one gcc 4.9, etc. At the gcc >= 5 era, it means we want to package only one 5.x version, one 6.x version, etc. If you want to fix the problem without waiting for gcc 5.4, what I can suggest is to backport the fixes for the regression you are experiencing.
