I was able to reproduce. It looks like C++20 adds some new capability to the equals operator (e.g. [default equality](https://en.cppreference.com/w/cpp/language/default_comparisons), inequality) but adding these features has caused some new restrictions on the equality operator. Namely, if `a == b` is legal then `b == a` must be legal. The way we were adding equality with `util::EqualityComparable` didn't quite fit those rules but we can make it work. -- This is an automated message from the Apache Git Service.
