In case the caller also sets the flip vertically flag, it continues and calls `stbi__vertical_flip_slices` with the null pointer result value and the uninitialized `z` value.

En caso de que la persona que llama tambi\u00e9n establezca el indicador de giro vertical, contin\u00faa y llama a `stbi__vertical_flip_slices` con el valor de resultado del puntero nulo y el valor `z` no inicializado.
