...which raises the interesting question if, and how, weak function pointers work before relocation.
Has anyone ever tested / analyzed this?
Weak symbols are a compile-time thing, not a run-time thing. The linker discards weak symbols if a "regular" symbol with the same name is found, that's all. So it's actually link-time, rather than compile-time :-).
