Hacked GDB Dashboard Puts It All on Display
There are a lot of these types of tools already in the reverse engineering community (in order of lowest chance of breaking when you throw really weird stuff at it):
GEF: https://gef.readthedocs.io/en/master/
PWNDBG: https://github.com/pwndbg/pwndbg
PEDA: https://github.com/longld/peda
They also come with a slew of different features to aid in RE/exploit dev, but many of them are also useful for debugging really weird issues.

Debugging with GDB
GDB is great. I definitely recommend checking out watchpoints as well, a very useful tool for monitoring how a variable changes over time.
GDB also has many good plugins - pwndbg has tons of features and UI improvements over stock GDB.

Making GDB Easier: The TUI Interface
I've recently started a new semester for my Master's program, and the first project for the semester involves using the GDB tool (GNU Debugger) to analyze a stack on a simple C program that contains a buffer overflow vulnerability. A couple of semesters ago, I had been given a VM pre-loaded with a more featured debugger tool called pwndbg. Pwndbg was excellent because it was easy to use and easily allowed accessed to information such as current assembly code being executed and a view of the program registers. So, going back to using GDB felt a little like stepping back into the stone age.
