This is a feature I would like to see.

I actually think that something like that is the way to go. It's
closely related to what Dan wrote about in:
and I'd like to have a go at implementing option #2 in that mail.
That (the frame unwinder end-of-stack method) wouldn't actually help
with this problem; that's why I sent the two separately (they were
originally the same message when I was writing it). The architecture
unwinder could report a saved pc of zero as terminating the stack, but
in all the cases I'm interested in, the DWARF-2 unwinder is actually
used for the bottom frame.
Unfortunately I'm leaving for a a four-week trip tomorrow. I won't be
able to read my mail for most of the time between now and june 17.
Well, enjoy your trip. I have a thousand different things that need
merging, and I'll be working on them over the coming weeks; but it
won't do me any harm to table this one until we have time to discuss it
further, as long as we've deliberately postponed it rather than let it
fall through :-)
So, I shall not pursue this patch right now, and we'll discuss it later
(probably not until July; the GCC Summit at the end of June is going to
wreck my schedule around when you get back). Thanks for all the
