--- Comment #1 from lu_zero at gentoo.org <lu_zero at gentoo.org> ---
One of the problems I'm seeing with your code is that you are using malloc,
while swscale requires aligned memory to operate.

You can use av_image_alloc to directly allocate the right amount of memory for
the image and have the linesizes/strides computed at the same time.

I checked your code updated to use av_image_alloc and ASAN does not spot
errors.

Using av_image_alloc solves your issue?
