FFmpeg/tests/checkasm/hevc_pel.c
Andreas Rheinhardt 09408539f4 checkasm/hevc_pel: Fix stack buffer overreads 
This patch increases several stack buffers in order to fix
stack-buffer-overflows (e.g. in put_hevc_qpel_uni_hv_9 in
line 814 of hevcdsp_template.c) detected with ASAN in the hevc_pel
checkasm test.
The buffers are increased by the minimal amount necessary
in order not to mask potential future bugs.
