From d97c8b8239e8b3c5ddb951d427b7d78ea7faad25 Mon Sep 17 00:00:00 2001
From: Sergei Trofimovich <slyfox@gentoo.org>
Date: Sun, 30 Jul 2017 23:08:02 +0100
Subject: [PATCH] OTHER: _xmmsv_dict_hash: make hash function
endianness-agnostic
The following code:
uint32_t k;
memcpy (&k, data, sizeof (k));
computes different data depending on platform endianness.
That causes test_xmmsv_serialize_coll_match test to fail
as collection order is serialized in wrong order.
