5624 # compiler is going to actually follow the language spec like it's
5625 # supposed to, instead of not following it like old buggy versions
5626 # did. There's absolutely no reason to turn this on.

5630 # It's commonly useful to pass |this| to objects in a class'
5631 # initializer list. While this warning can catch real bugs, most of
5632 # the time the constructors in question don't attempt to call methods
5633 # on the passed-in pointer (until later), and annotating every legit
5634 # usage of this is simply more hassle than the warning is worth.

5641 # on program correctness and there's no real reason to waste time
5642 # trying to prevent it.

5655 # Chromium code compiles without exception support. We therefore have
5656 # to use setjmp/longjmp for e.g. JPEG decode error handling, which
