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.
