--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The documentation now has:
Note that sanitizers tend to increase the rate of false positive
warnings, most notably those around @option{-Wmaybe-uninitialized}.
We recommend against combining @option{-Werror} and [the use of]
sanitizers.
