[Discuss-gnuradio] Lock/Unlock segfaulting

[Achilleas Anastasopoulos]

I have a pyhton program (see http://web.eecs.umich.edu/~anastas/docs/onoff_flat_test.py)
that based on a button chooser (on/off) rearranges itself.
I use lock/unlock to do the disconnection/reconnection.

However, I always get segfaults after a couple of changes.

The graph is pretty simple:

A complex sinusodial source + noise (throttled) goes to either:

ON) multiplication by 2 and complex to mag squared

or

OFF) multiplication by 0 and complex to mag squared

and then to a null sink.

I would really appreciate some input because I am kind of lost as to what

is going wrong.

thanks in advance,
Achilleas
