Subject: [PATCH] Only write audio data to a temporariy file in debug builds
This isn't useful in regular builds and is actually a security concern,
although it seems (see discussion in [Bug-Debian]) that this is most likely
only reached during testsuite calls.
CVE-2014-0027
Original patch from Rui Matos <tiagomatos@gmail.com>
