What USE flags are enabled for chromium? You haven't specified that you're using the custom-cflags USE flag, so whatever's in your global CFLAGS setting is largely irrelevant. Also, you don't need to specify --as-needed; that's default, now. I don't know what those other flags are doing. Start with revdep-rebuild, see if that fixes it. If not, you probably ought to re-emerge chromium and its direct dependencies. Given your recent experience with overclocking and the rather correct warnings about silent data corruption, you may need to re-emerge a lot more than that. -- :wq
