It is currently very fragile, due to:
* Differing versions of compilers/DWARF version result in a variety
of breakages in the our code which analyzes the DWARF info;
* With musl, libunwind seems to be currently unable to traverse
beyond signal handlers, due to the DWARF information not
being present in the signal frame.
See <https://maskray.me/blog/2022-04-10-unwinding-through-signal-handler>.
Note that I have not verified that the problem in the blog
post above is indeed what we're hitting, but it seems plausible.
