> GDB has an extensible, modern C++ codebase with literal decades of hard earned knowledge baked into it.

I literally laughed outloud at this. Have you ever actually opened a GDB source file? It is, as a whole, extremely poor quality code. Almost all of it is doing C string manipulation and raw pointer arithmetic; almost none of it uses C++ smart pointers, nevermind the rest of "modern C++"; the vast majority is completely uncommented, and "literal decades of hard earned knowledge" can be better translated as "literal decades of historical baggage, cruft, and hacks". I regularly cause GDB to segfault in normal, mundane operations.
