From caa0f6c623214231380c5ef0de91b53cc43d1e0b Mon Sep 17 00:00:00 2001
From: NeilBrown <neilb@suse.de>

Subject: [PATCH] Fix gcc-4.4 compiler warning.
Apparently the dereferencing of a type-punned pointer breaks strict
aliasing rules. And we wouldn't want to do that.
So just make a different array of the appropriate type and use memcpy.
