[Discuss-gnuradio] buffer taps

[MHMND Herath]

Dear sir
    I want to implement a buffer. How can I do it? Can I use taps. I wrote it
as a queue. first queue.push();
then take queue.front()
to remove queue.pop()
But i create a segmentation fault (core dumped)
Can you explain why?
And how to implement queue in a c++ processing block
Thanks
Neil
