--- Comment #12 from Ozkan Sezer <sezeroz at gmail dot com> 2012-01-03 16:54:00 UTC --- (In reply to comment #10) > It's also questionable to cause new warnings to appear on the branch if > you consider code using -Werror. gcc-4.4 used to warn (see bug 50950), therefore if someone's build is using -Werror and added such uninitialized vars to his code _after_ beginning to use gcc >= 4.5, he is not getting the error despite the fact that he wants to.
