From 590743101dc934043f34013f1c9bb9fb261355b0 Mon Sep 17 00:00:00 2001 From: Andreas Cadhalpun Date: Thu, 18 Jun 2015 20:15:12 +0200 Subject: [PATCH] postproc: fix unaligned access QP_store is only 8-bit-aligned, so accessing it as uint32_t causes SIGBUS crashes on sparc. The AV_RN32/AV_WN32 macros only do unaligned access in the HAVE_FAST_UNALIGNED case.
