This was mostly a learning project for me. I now understand the eBPF unwinding code and coredump testing infrastructure a lot better (it's very cool). More work would be needed to turn this into a proper patch. The way it's currently implemented doesn't really provide any benefits, but I think in theory frame pointer unwinding could greatly decrease the amount of stack delta memory needed when dealing with large Go applications. For now I don't plan to continue with this, but I'm uploading this patch in case somebody else feels inspired to continue at some point ...
