I didn't. I've a hunch that it's a very deep rabbit hole, which means understanding and fixing those crashes is going to be a significant time investment. I can't bill a customer for that time, and my boss won't be able to pay my salary if I spend weeks studying and fixing broken old debuggers instead of doing the work a customer pays for. Either way, the debugging experience without something like rr sucks hard when it comes to heavily multi-threaded, asynchronous, event-driven systems. So even if gdb didn't crash, its usefulness is very limited compared to simple tracing.
