The revert itself broke a rather simple buffersrc->buffersink case as 

ffmpeg -f lavfi -i "testsrc[out0];sine[out1]" -bsf:a noise=dropamount=1 out.avi

ffmpeg is now consuming all memory, it seems video frames are stuck in the 
filter graph forever.

(the dropamount parameter to the noise bitstream filter was just committed 
to be able to drop all packets of a stream)
