Comment (by kurosu):
Thank you.
The pointers and strides have the expected alignment, look valid, and seem
to be within bounds (ie rsi/rdi are between dest_y/ptr_y and dest_y/ptr_y
+ 16 * linesize). Might then be an allocation problem (buffers actually
not that big?).
Unfortunately, I can't reproduce the crash under Win64 or Win32.
