What I've found out so far is that the tree built in the 'install' directory (./install/usr) is not suitable to live side-by-side with /usr/ on the host machine. My original approach (documented on http://dev.iachieved.it/iachievedit/) was to ball everything up into a .deb package that installed as an overlay to /usr/, this was just to make it simple to get started.
Now with swift-2.2 and swift-3.0 and the possibility one might want to use both (python2.7, python3), I'm going to change over to placing in /opt/swift/VERSION and provide some alternatives mechanism, OR, use the approach that python2.7, 3, etc. use where there is a /usr/bin/python2.7/, /usr/lib/python2.7/, etc. and /usr/bin/python links back there.
tl;dr: I don't know what occurs exactly but the equivalent of rsync -a ./install/usr/ /usr/ (overlay) causes mayhem for starting the REPL.

I've just noticed (thanks to you Ryan) that compiler-rt is indeed checked out and included in the 14.04 build but not the 15.10. I'm going to rebuild from the ground up on 15.10 to see if it grabs compiler-rt and reproduces, as this is being checked out by the ci.swift.org <http://ci.swift.org/> CI server.
This error occurs before any downstream packaging (deb) and is failing the build itself (on the test REPL, it can't even load). Will report back in a bit.

Well, I thought the REPL issues had all been put to rest, but now I am seeing this on Ubuntu 14.04 (15.10 I do not see it):

==18928==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.
This is with the "master" branches that build Swift 3.0, hashes:
$ swift swiftrevs.swift
Is anyone else building the world on Ubuntu 14.04 that can verify this?
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 <http://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.
