It sounds like some bug earlier, because offline functions are accounted to have size of 1, see estimate_function_body_sizes: /* Estimate static overhead for function prologue/epilogue and alignment. */ int size = 2; (later the value is divied by two) I will try to debug why this value is no longer accounted.
