--- Comment #6 from Kostya Serebryany <kcc at gcc dot gnu.org> --- adding attribute ctor to __asan_init is questionable - windows has different syntax. - running non-instrumented binary w/o calling __asan_init at startup is risky: the binary may call memset/etc an touch shadow memory, which is not initialized before __asan_init
