Re: [Swift CI] Build Still Failing: 0. OSS - Swift Incremental RA - Ubuntu 16.04 (master-llvm-swift5-transition) #407

Same error here, related to PCH:

<unknown>:0: error: compilation involves pch was disabled in PCH file but is currently enabled

Geez. I haven’t a clue, I can look, but I wager this is a perturbation arising from something Bruno was fiddling with (at least, in that set of changes). The error originates in clang anyway, though of course for bridging PCH we’re driving clang so … could be us.
