Issue Description:

In all DEVELOPMENT-SNAPSHOT toolchains released after 09-07 I am seeing a consistently reproducible crash during compilation.

https://github.com/PerfectlySoft/Perfect-HTTPServer.git

The above repository, when built with SPM, will generate the following crash (note that this report is made with 09-11 since the chains after that do not seem to spit out the full back trace). The crash is always consistent. The latest toolchain I tested with is 09-15. I have not tried this on Linux.

For what it's worth, this bug is also consistently hit on Linux (Ubuntu 16.04) with swift-DEVELOPMENT-SNAPSHOT-2016-12-07-a
