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

[Naceur]

Hello GNU-Radio list,

I wonder why is my C++ code is thorwing a segmentation fault (core dumped),
gdb outputs:

Program received signal SIGSEGV, Segmentation fault.
0xb7b1b718 in
gr_hier_block2_detail::connect(boost::shared_ptr<gr_basic_block>, int,
boost::shared_ptr<gr_basic_block>, int) ()
   from /usr/local/lib/libgnuradio-core-3.6.5.so.0.0.0

I confirm that the same line of code which is throwing that error is
executed multiple (randomly) times before it came to that error.

I can't figure out what is causing that and how to fix it ?   
All explanation are welcome.

Regards,
