I don't know of a memcpy() implementation that would actually bail out

This isn't a bug, and I see no reason to clutter the code just to shut
up valgrind.

Isn't memcpy on overlapping (even entirely overlapping) buffers undefined behavior unless the count is 0?

On my Linux box the man page says:

The memcpy() function copies n bytes from memory area src to memory
area dest. The memory areas may not overlap. Use memmove(3) if the
memory areas do overlap.
