Description: use alignment-safe buffer handling.
Currently we are using assignment to copy the contents of a variable of
arbitrary type into a buffer, but this is not portable because the buffer
address may not be aligned. Use memcpy() instead, which should be
comparable performance ut alignment-safe.
