Hi, this series should hopefully fix the issue with __strstr_arch13(), which Claudio reported. I have to admit I did not manage to fully reproduce it, but at least with this change the traces of a simple test from TCG and real hardware match.
I've also fuzzed the changed helper and strstr() itself; not sure whether anything generic may come out of it, but here are the links anyway [1] [2]. Patch 1 makes glibc pick __strstr_arch13() in qemu-user, patch 2 is the fix and patch 3 is the test (generated from Claudio's strings and further fuzzer's findings).
