When LLVM was updated to a new enough release to have GWP-Asan, we
started getting probabilistic test failures, as the double-free would
sometimes be caught by GWP-Asan (odds are about 1/5000).
We should tolerate either output.
In some sense it's hard to validate that this change actually works, but I feel confident we'll know after a week or so.
