This might well be an issue with libunwind.  I was debugging a very
similar backtrace at work (Linux and xvfb instead of NetBSD and X.Org,
but also aarch64) and it ended up being an issue in libunwind.
Updating to a more recent release of libunwind helped, but I can try
to track down the commit that fixed things, perhaps that's enough to
fix this for you too.
