It's hard to help you with so little information. But the bad news
is that I'm going to be either extremely busy or even unavailable
in the next few weeks. Hopefully someone else might have some leads
for you.

In the meantime, what you can do to learn more about how things work
in GDB is, if you have access to a cheap GNU/Linux machine, or even
a Windows machine, is debug GDB with itself while GDB is computing
a backtrace. It starts at get_prev_frame... You could compare what
the working implementation does with what your implementation does,
and see where things start breaking down on your side.
