Looks like this fell through the cracks of our CI because this requires a combination of hardening mode = Debug and C++03. I don't think it makes sense to add that combination specifically, though -- while we should test all combinations in theory, in practice this is not feasible due to combinatorial explosion. So I think I'll take the patch as-is without increasing test coverage.
