ffmpeg | branch: master | Thomas Turner <thomastdt at googlemail.com> | Tue Dec 27 18:43:19 2016 -0800| [1bfb4587a2e5b25ed15f742149e555efc8f305ae] | committer: Michael Niedermayer

avutil/tests/audio_fifo.c: Memory leak and tab space fixes

Prevents memory leak when read_samples_from_audio_fifo() is
called more than once by deallocating before reallocating
more memory.

Fixes space indentation for contents in ERROR().
