In this example, a VLA of size s is declared. In accordance with recommendation INT01-A. Use rsize_t or size_t for all integer values representing the size of an object, s is of type size_t, as it is used to specify the size of an object. However, it is unclear whether the value of s is a valid size argument. Depending on how VLAs are implemented, s may be interpreted as a negative value or a very large positive value. In either case, this may result in a security vulnerability.
