ISO C++ rejects 's.f(1)' as ambiguous when both 'void f(int)' and 'void f(int, int = 0)' are declared on S. The previous resolver returned the first viable candidate via pickOverload's fallback. Extended isOverloadAmbiguousAfterNormalization to take an optional argCount: when provided, the predicate compares only the first argCount slots of each candidate's parameterTypes. Candidates whose declared-prefix matches up to argCount are treated as ambiguous because default arguments make all of them equally viable for the call. Without argCount, behavior is unchanged (the original int/long normalization-collapse contract, full-length equality required). pickOverload now passes site.arity so default-arg ambiguity fires. Test: cpp-overload-default-arg-ambiguous fixture. s.f(1) where S has f(int) and f(int, int = 0) asserts exactly .toBe(0) CALLS edges. Passes under both REGISTRY_PRIMARY_CPP=1 and =0. All 2114 resolver integration tests pass; all 148 cpp tests pass under both modes. |
