Sorry, I'm not sure exactly what you are asking.
The value returned by runtime.Callers is just a slice, and the value
returned by runtime.CallersFrames is an ordinary value. It's fine to
save those values however you like.

Not sure if it the same issue, but one problem is that runtime.CallersFrames returns a *Frames, which means it does an allocation. It would be nice to have a call that either returned a Frames by value, or one that takes a frame to reset and fill in.
