From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The way we were casting small (<32bit) integers was broken on big endian hosts, causing stack smashing. This was detected in the test suite either by test failures due to incorrect results, or by libc/gcc abort'ing with its stack canary triggered. Signed-off-by: Daniel P.
