The quickest solution is just add a pragma to shut it up.

Find where selectNodes() is defined. Add
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wdangling-reference"
before the definition, and
#pragma GCC diagnostic pop
after it.
That's what I ended up doing, it turns out there were structures like this in about 7 places in that file and several more in another, it just got through two before the build failed previously. I ended up using the approach for the whole file and then fixed a couple of #include <cstdint> since you don't get it for free anymore and the build completed.
Thanks!
