MODERATORS
Except the C++ "Core dumped" line is telling you it just wrote a file out with the full state of the program at the time of the crash, you can load it up and see where it crashed and then go and look at what every local variable was at the time of the crash.
Pretty sure you can even step backwards in time with a good debugger to find out exactly how you got to the state you're currently in.
Where does it write the file
If you are using systemd, there's a tool called coredumpctl.
