This is great. Very creative. Many should copy this scheme. The key is the relative-to-executable/shared object base stack trace program counters.

bun is statically linked, yes? In a dynamically linked system one would need to prefix every normalized program counter with a small numeric shared object ID.

It's not really anything new. Very common in environments where you can't ship symbols such as games crashing on player's computers.

For example, the Unreal Engine crash reporter has been capable of sending such a simple format for many years. You can restore a reasonably accurate function/line number from it for each stack frame.

Though minidump is usually preferred as having the stack variables can give additional hints to what happened.
