I fixed both of those now, but to no avail. The build still fails. But looking at the error it's interesting to note that "do_yield_thread" does exist, but "do_yield_thread_reload" does not. From what I can figure out, this "_reload" function is generated by asmgcroot. My OSX build is defaulting to shadowstack. I switched all builds to use shadowstack and the build error goes away. So I guess that was the issue.

Also, did you mean "_cleanup_()" instead of "__cleanup__()"?
