This puts ff_fast_malloc() and av_fast_malloc() in line with av_fast_realloc() Signed-off-by: James Almer <jamrial@gmail.com> --- Now freeing the buffer on error, since that's what the doxy for av_fast_malloc() states is meant to happen. libavutil/mem_internal.h | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-)
