I have seen this behavior many times in many scenarios. Almost always it
has to do with a build parameter.
Recently I have noticed that compiling with the "compiler-rt" project
seems to cause this issue frequently. I do not understand what "compiler-
rt" is, or what its value to Swift is, so I just omit it from my builds.
It maybe worth while to do the same and rebuild and see if it goes away.
I would think that if "compiler-rt" is the source of the issues then
something likely needs to be submitted to bugs.swift.org.
Another thing to check is if your packaging Swift (dep, rpm, pacman,
etc...) that you are do not strip symbols from binaries and libraries as
part of packaging.
