see comment #3

For the record, I build the sanitisers on all systems > Darwin10/macOS 10.6
(where it's no longer supported upstream and is now pretty broken).

However, I don't build all the older systems that often - but (for example) -
see https://gcc.gnu.org/ml/gcc-testresults/2019-02/msg00055.html

So .. I agree that we have test issues with headers [ comment #4 ] (and those
need resolving in a general way, not piecemeal) - but AFAICT bootstrap is not
broken on current 10.13.

[maybe someone is using a different version of the SDK from me?

if so, please be specific about the version of Xcode and the SDK in use,
thanks.]
