This function will use gcc's function __builtin_dynamic_object_size and __builtin_object_size Its function is to obtain the size of the object through compilation, so as to judge whether there are out-of-bounds operations in commonly used functions. It should be noted that the option -O2 and above is required to enable this function Signed-off-by: anjiahao <1090959677@qq.com>
