    // The destructor can safely access mRefs because either it's deleting

    // mRefs itself, or it's running entirely before the final mWeak decrement.

    // Since we're doing atomic loads of `flags`, the static analyzer assumes

    // they can change between `delete this;` and `refs->decWeak(id);`. This is

    // not the case. The analyzer may become more okay with this patten when

    // https://bugs.llvm.org/show_bug.cgi?id=34365 gets resolved. NOLINTNEXTLINE
