0edf96c28f string/tester memrchr test 
http://sourceware.org/ml/libc-alpha/2013-08/msg00095.html

I found this useful at one stage when I was seeing a huge number of
memrchr failures all of test number 10.

	* string/tester.c (test_memrchr): Increment reported test cycle.

e0f7a38046 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.

303e567a80 Check for integer overflow in cache size computation in strcoll 
strcoll is implemented using a cache for indices and weights of
collation sequences in the strings so that subsequent passes do not
have to search through collation data again.  For very large string
inputs, the cache size computation could overflow.  In such a case,
use the fallback function that does not cache indices and weights of
collation sequences.

Fixes CVE-2012-4412.

141f3a77fe Fall back to non-cached sequence traversal and comparison on malloc fail 
strcoll currently falls back to alloca if malloc fails, resulting in a
possible stack overflow.  This patch implements sequence traversal and
comparison without caching indices and rules.

Fixes CVE-2012-4424.

Check wheter the compiler has the option -fno-tree-loop-distribute-patterns
to inhibit loop transformation to library calls and uses it on memset
and memmove default implementation to avoid recursive calls.
