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.
