[swift-lldb-dev] [Swift CI] Build Failure: 0. OSS - LLDB Incremental - OS X (master) #4852

[Alex L]

I think this failed because of CI incremental build issues where some files
weren't recompiled when they should've been re-compiled, and thus the
linked clang binary becomes broken since the diagnostic IDs in some TU are
outdated. This leads to assertion failures like the one that tripped up
this build. More info here: rdar://problem/29201272.
