--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Apparently, it's a very old issue, started with GCC 5.1.0:
$ cat 1.ii
namespace xercesc_2_7 {
class XercesDOMParser {
void resetEntities();
};
void XercesDOMParser::resetEntities() {}
} // namespace xercesc_2_7
$ cat 2.ii
namespace xercesc_2_7 {
class XMLErrorReporter {
public:
virtual ~XMLErrorReporter();
};
class XMLEntityHandler {
virtual void resetEntities();
};
class AbstractDOMParser : XMLErrorReporter, XMLEntityHandler {};
class XercesDOMParser : AbstractDOMParser {
void resetEntities();
};
inline void XercesDOMParser::resetEntities() {}
} // namespace xercesc_2_7
$ g++ -flto=16 -O2 -fno-inline 1.ii 2.ii
