stb_image is a single file MIT licensed library for processing images. It may look like stbi__load_gif_main
doesn’t give guarantees about the content of output value *delays
upon failure. Although it sets *delays
to zero at the beginning, it doesn’t do it in case the image is not recognized as GIF and a call to stbi__load_gif_main_outofmem
only frees possibly allocated memory in *delays
without resetting it to zero. Thus it would be fair to say the caller of stbi__load_gif_main
is responsible to free the allocated memory in *delays
only if stbi__load_gif_main
returns a non null value. However at the same time the function may return null value, but fail to free the memory in *delays
if internally stbi__convert_format
is called and fails. Thus the issue may lead to a memory leak if the caller chooses to free delays
only when stbi__load_gif_main
didn’t fail or to a double-free if the delays
is always freed
