[Discuss-gnuradio] Change in 3.7 with buffers

[Luke Berndt]

Sorry - I seem to keep running into weird corner cases with my program. I am 
having an issue were I am trying to run multiple graphs off the same source, 
and decoding different channels digital audio to wav files. It worked great 
under 3.6, but with 3.7 they are cutting off prematurely. 

I will keep digging deeper, but I just wanted to check first to see if this has 
happened to anyone or if there were any obvious changes to blocks. If there 
anything new and special I might have to do to flush buffers in blocks once I 
tell it to stop recording and close the file? I am using wav_file->close();. It 
is a pretty standard graph using quad_demo to a gr_DSD block to decode the 
digital audio and then a wav_file_sink.
