It seems after this patch I got an infinite loop if I try to convert the 
attached file using this command line:

./ffmpeg -i amerge-test.mov -filter_complex "[0:a:0][0:a:1]amerge=2[aout]" 
-map "[aout]" out.wav

Note that in my build FF_BUFQUEUE_SIZE in libavfilter/bufferqueue.h is set 
to 256, because otherwise it errors out with ENOMEM, but that also happens 
with the old filtering code. On the other hand, the old filtering code and 
FF_BUFQUEUE_SIZE set to 256 does allow the file to properly convert.
