The error occurs with gcc 11.2 not 11.1 used in for your tests. For clang it starts with version 13

As I said, I tried it locally with GCC 11.2 and Clang 13.0.1, neither of them shows this error.

using this newer catch.hpp (https://github.com/catchorg/Catch2/releases/download/v2.13.8/catch.hpp) solves the problem
