  Unfortunately, there is no workaround for this other than to
  upgrade/downgrade Xcode or to build upstream Clang yourself.

  In particular, Xcode 11 Beta 1 to Beta 3 are known to be affected. While
  Xcode 11 Beta 4 to Xcode 11.3 work, the bug was unfortunately reintroduced in
  Xcode 11.4.1 and a fix is not expected before Xcode 11.6.
  Xcode 11.4.1 and was only fixed in Xcode 12 Beta 1.

  You can get older versions of Xcode
  [here](https://developer.apple.com/download) by clicking on "More" in the
  top-right corner.
