string/test-memcpy error reporting
http://sourceware.org/ml/libc-alpha/2013-08/msg00094.html
Using plain %s here runs the risk of segfaulting when displaying the
string. src and dst aren't zero terminated strings.
* string/test-memcpy.c (do_one_test): When reporting errors, print
string address and don't overrun end of string.
