I've seen three different intermittent misbehaviors in my application which

buffered between two blocks (A-B) when that connection is removed? Are they
discarded, delivered to B, or delivered to whatever A's output is now?)

imaginary input unconnected, implicitly zero), then multiply it with the sine.

that there are also, of course, non-OSX audio sinks/sources; I don't know
how they signal failure to the caller but it should be made the same on all
platforms. If there's an existing failure-signaling path for non-OSX then we
should just use that everywhere.)

to warn on ought to be exposed to
the caller, not just stderr/stdout, if nothing else so that non-console-based
applications can communicate the information to their actual user interface, as
well as performing appropriate error handling.

The wait() occurs last so that what it is waiting for is only for the stop() to
complete, not for anything else.

Since the preceding multiply_conjugate should square the magnitude
with the behavior, and a
screenshot of what the demodulated output looks like just at the threshold of
failure (the signal is 200 samples per cycle).

idiomatic C++.)
I hope someone who has a working GNU Radio development environment (I've tried
and failed, which is an unrelated problem) can try this fix.
