Re: [Discuss-gnuradio] free(): invalid pointer for AM demod block at Gnuradio 3.7.13.5

[Volker Schroer]

You have set passband frequency to 0 ! So your passband reaches from 0
to 0. That make no sense. Probably a parameter check should be
introduced to the demod block Further  you should add a throttle block
after your source.

Same problem can be found in 3.8.
