<div>Is anyone else building the world on Ubuntu 14.04 that can verify this?<br></div>

<div>I have seen this behavior many times in many scenarios. Almost always it has to do with a build parameter.<br></div>
<div> </div>
<div>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.<br></div>
<div> </div>
<div>I would think that if "compiler-rt" is the source of the issues then something likely needs to be submitted to bugs.swift.org. </div>
<div> </div>
<div>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.<br></div>
