[swift-dev] [Swift CI] Build Failure: 0. OSS - Swift Incremental RA - Ubuntu 16.04 (master) #897

We keep seeing this failure in the bots:

src/libdispatch.so: error: undefined reference to ‘_T0s17_assertionFailures5NeverOs12StaticStringV_SSAE4fileSu4lines6UInt32V5flagstFTfq4nxnnn_n'

A clean build fixes it. However, it comes back, because if the bot builds the 4.0 branch and then goes and builds master, the problem returns.

Can somebody look at this?
