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.

and if I try to use AM demod block with anything the flowgraph crashes
with this:
Warning: This flow graph may not have flow control: no audio or RF hardware blocks
found. Add a Misc->Throttle block to your flow graph to avoid CPU congestion.
Executing: /usr/bin/python2 -u /home/feanor/Development/SDR/top_block.py
free(): invalid pointer
Done
This is just a AM demod block with null sink and null source attached
to it, reproduction flowgraph is attached to this email
