In the C++ frontend, the lookup_destructor function now correctly passes the complain flag down to the lookup_member function. While this change does not fix any existing issues, it improves the handling of SFINAE (Substitution Failure Is Not An Error) diagnostics by ensuring that error reporting is consistently propagated during member lookups.
