Reproduce the failure with the repository's CMake build using g++ 15, then inspect src/passes/Strip.cpp around the constructors reported in the diagnostic. Compare the warning and compiler-option behavior with the project's build configuration; done means the project compiles successfully with g++ 15 without treating these diagnostics as errors.
