I am trying to debug an OOT in gnuradio 3.8 using gdb. It's a problem with double free() that seems to have popped up with 3.8.2
I rebuilt my OOT with debug symbols. WIthout gdb, it all runs, but of course tells me about the double free() when it shuts down. 1. I've altered the top_block.py to stop and wait after printing the process id before continuing, then enter to continue. This starts up the flowgraph GUI. 2. In a different terminal window: $ sudo gdb -p the_process_id This makes the gui disappear, and 'System Problem Detected' window appears asking if I want to report the problem. I still have the gdb window, but because I was not able to shut down my GUI, the backtrace does not let me look at the shutdown error I am getting. -- Tom, N5EG
