From d4f2a6250aa0598a4a6414a3eb34e4f462b290b0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?M=C3=A5ns=20Rullg=C3=A5rd?= Date: Tue, 24 Feb 2009 01:41:44 +0000 Subject: [PATCH] Fix get_ur_golomb_jpegls() with A32_BITSTREAM_READER If k==0, log==0 can indicate that the coded value uses more than MIN_CACHE_BITS bits. With MIN_CACHE_BITS==32, the fast branch is incorrectly taken in this case unless explicitly forbidden.
