Comienza con src/util.h alrededor de las líneas 506-507 y test/cctest/test_util.cc alrededor de la línea 229, y reproduce la advertencia en la toolchain de macOS indicada. Sigue la instanciación de MaybeStackBuffer e identifica la ruta de API de C++ compatible; se considera terminado cuando la compilación de pruebas afectada ya no emita estas advertencias de obsolescencia.
