put_signed_rect_clamped uses different types for differnt 8bit and >8bit content. The 8bit SSE2 function used the real type in its function signature; this does not coincide with the array of function pointers it gets put into and therefore also not with how it is called which is UB. Also, casts of function pointers to void* like it is done here are not legal ISO-C as function pointers and object pointers need not be convertible. So just declare the function to have the required type for the function pointer array. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
