--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note the documentation has the following warning about warnings and sanitizers:
```
Note that sanitizers tend to increase the rate of false positive warnings, most
notably those around -Wmaybe-uninitialized. We recommend against combining
-Werror and [the use of] sanitizers.
```
