--- Comment #3 from labath at google.com ---
In DWARF v4 there seem to be two separate problems. One is that the call stack
reconstruction fails -- we don't find the "fake_main" frame. This is probably
due to a missing support for some of the GNU extension attributes, and I'm
guessing that fixing that will make the value come out right.

The second problem is that we display a bogus value in the case when the call
stack is incomplete.
