[swift-dev] [Swift CI] Build Failure: 0. OSS - Swift Incremental RA - OS X (master) #7592

[Slava Pestov]

Looks like a non-deterministic failure. Could be the same root cause as https://ci.swift.org//job/oss-swift-incremental-RA-osx/7570/consoleFull#577085863ee1a197b-acac-4b17-83cf-a53b95139a76 <https://ci.swift.org//job/oss-swift-incremental-RA-osx/7570/consoleFull#577085863ee1a197b-acac-4b17-83cf-a53b95139a76>
(an ErrorType popping up here would trigger the ‘forming CanType out of non-canonical type’ assert).
