--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Please note this part of the documentation: 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. https://gcc.gnu.org/onlinedocs/gcc-13.2.0/gcc/Instrumentation-Options.html#index-fsanitize_003daddress
