My recommendation is to, by default, refuse to compile with newer (i.e., worse)
gcc versions than you have tested, and tell the builders that overriding that
has a significant chance to result in a broken build.  You might also choose
not to use worse gcc versions for your own development, saving you the time to
find and work around the new bugs that gcc's miscompilation introduces.
