And any class with a pointer, I suspect.

This is a reduced/simplified example from our codebase still triggering the
error even with 59bfdd5f467292a368d0d628084a4b65d1bb06bb:

$ cat test.cpp 
struct ArrayRef
{
    ArrayRef(int* ptr) : ptr_(ptr) {}
    int& operator[](int n) const { return ptr_[n]; }
    int* ptr_;
};

int main()
{
    int        a;
    const int& r = ArrayRef(&a)[0];
}

$ g++ -std=c++17 -Wdangling-reference test.cpp -o test
test.cpp: In function ‘int main()’:
