anton at mips dot complang.tuwien.ac.at changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |anton at mips dot complang.tuwien. | |ac.at --- Comment #8 from anton at mips dot complang.tuwien.ac.at --- 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.
