<div class="">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 class=""></div>
<div class=""> </div>
<div class="">I would think that if "compiler-rt" is the source of the issues then something likely needs to be submitted to <a href="http://bugs.swift.org/" target="_blank" class="">bugs.swift.org</a>. </div>

<div class="">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 class=""></div>
