 Summary of the bug:

 Decode errors are visible in an h265 stream that has intra-refresh
 encoding present.  The decoded stream looks error-free when decoded by the
 JCT-VC reference software as well as by amlogic (odroid-c4) hardware
 decoding.  No decoding errors are reported by ffmpeg

 How to reproduce:
 {{{
 % ffmpeg -report -v 9 -loglevel 99 -i intrarefresh_decode3.h265
 decoded.yuv

 }}}

 Version is built from current git-master on arch linux x86_64, but the
 decode errors are also visible on VLC 3.8 Windows:
