SInce the update I have been getting memory error messages in the gnuradio-companion terminal window.
Have commented out all instances of delete [] in my destructors, but no change to the errors. No instances of free() in my code.
The errors occur after stopping the flowgraph from gnuradio-companion.
I was able to catch the "corrupted size vs. prev_size while consolidating" error using gdb (OOT built with -DCMAKE_BUYILD_TYPE=Debug).
Thread 1 "python3" received signal SIGINT, Interrupt.
