Re: [Discuss-gnuradio] Segmentation fault issue with gr_hier_block2_detail::connect

[Marcus Müller]

Could you provide us with a backtrace (in GDB: "bt") and if possible with the 
code that you use to produce this error.
Usually, connect does not cause segfaults, a problem arises if you a) connect a 
block that does not exist yet (eg. in its constructor) b) connect a block in 
multiple flowgraphs.

Greetings,
Marcus
