gcc12 has added -ftrivial-auto-var-init=<choice>, which specifies how automatic variables without an initializer should be initialized. The default choice is "uninitialized", which is the default C/C++ behavior. Alternatives are "pattern" and "zero". For improved debugging, helping to detect uninitialized uses, the "pattern" choice should be used.
