Hi @owenca, this change is causing a test failure in the sanitizer bot (https://lab.llvm.org/buildbot/#/builders/5/builds/43303), that is still failing as of your most recent fix de641e2 (https://lab.llvm.org/buildbot/#/builders/5/builds/43334). Can you please revert if you need time to investigate so that we can get the sanitizer bot back to green?
