    libstdc++: Cast -1 to size_t in <format> [PR119429]

    This avoids a runtime error from Clang's annoying -fsanitize=integer
    (even though it's not undefined and behaves correctly).

    libstdc++-v3/ChangeLog:

            PR libstdc++/119429
            * include/std/format (__format::_Scanner::_Scanner): Cast
            default argument to size_t.
