+Subject: [PATCH] ldb: Use deterministic order of dict for tests
+
+Test failed on s390x but there is a simple reproducer for any
+architecture
+
+    for i in {1..30}; do
+        PYTHONHASHSEED=random \
+        python2 -c 'import ldb; msg = ldb.Message(); msg.dn = ldb.Dn(ldb.Ldb(), "dc=foo29"); msg["dc"] = b"foo"; print(repr(msg)) '
+    done
+
+  ======================================================================
+  FAIL: test_repr (__main__.LdbMsgTests)
+  ----------------------------------------------------------------------
+  Traceback (most recent call last):
+    File "tests/python/api.py", line 2322, in test_repr
+      "Message({'dn': Dn('dc=foo29'), 'dc': MessageElement(['foo'])})")
+  AssertionError: "Message({'dc': MessageElement(['foo']), 'dn': Dn('dc=foo29')})" != "Message({'dn': Dn('dc=foo29'), 'dc': MessageElement(['foo'])})"
