At the end of the last post, DbgRs could finally set breakpoints. That was the last really critical feature needed for controlling execution of a program. Now that it can stop on an arbitrary function or code location, the next step is to find more information about the state of the program. In my opinion, the single most useful piece of information is the call stack, so that’s what this post will be about.

Very cool. I wonder how portable the theory behind it is. That’s one problem with the m1 macs, gdb doesn’t support them.
