ยง Debugging debug info in GHC

I wanted to use debug info to help build a better debugging experience within tweag/asterius. So, I was reading through the sources of cmm/Debug.hs. I'd never considered how to debug debug-info, and I found the information tucked inside a cute note in GHC (Note [Debugging DWARF unwinding info]):
This makes GDB produce a trace of its internal workings. Having gone this far, it's just a tiny step to run GDB in GDB. Make sure you install debugging symbols for gdb if you obtain it through a package manager.
