Read it:
void *memmove(void *s1, const void *s2, size_t n);
If s1 and s2 overlap, all bytes are copied in a preserving manner (unlike
memcpy())


And anwer the question: are s1 and s2 overlap in the str_repeat() ?
Why don't use memcpy() instead of memmove() ?

Because it's slower and we're copying to newly allocated memory anyway so things CAN not overlap. Also, your patch is the wrong way around.


Mybe I'm mistaken, but I think, that memmove() looks like that (without any error checks):

That's not what my glibc sources look like.
