It’s not just noise because it allows you to distinguish, e.g., between
same-named procedures.  As for frame addresses, it allows you to know
whether you’re actually going down the stack or not, for instance (GDB
gives that info too.)  So I find it quite valuable.

Now, perhaps it could be formatted in a more human-readable way?

I think we need input from the Gesier Meister here.  :-)

Thanks,
