With unbuffered on, there was no difference between my input and
output file.
With unbuffered off, there were a lot of small errors that were
introduced to the output file.
Is this a known issue, and should I always keep unbuffered on? gr3.7.6

If you unceremoniously terminate your flow-graph, there will be data in
'stdio' buffers that have not yet been committed to the operating system.
It may be the case, given Gnu Radio's internal buffering mechanism, that
using "unbuffered" all the time is the right thing to do, unless stdio
buffers offer a performance advantage for an application (Gnu Radio,
in this case) that already does alot of its own buffering.
