The virtual version is redefined in public subclass B. The non-virtual function is not found in subclass C of B. There is an easy workaround: don't overload function name. Error message: no matching function for call to `C::get_a (B &)' candidates are: int B::get_a() >How-To-Repeat: >Fix: Change name of one of the functions. >Release-Note: >Audit-Trail: >Unformatted: ----gnatsweb-attachment---- Content-Type: application/octet-stream; name="test4.cc" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="test4.cc" Y2xhc3MgQSB7CnB1YmxpYzoKICBBKCBpbnQgYSApIDogYSggYSApIHt9CnByb3RlY3RlZDoKICB2 aXJ0dWFsIGludCBnZXRfYSgpIHsgcmV0dXJuIGE7IH0KICBzdGF0aWMgaW50IGdldF9hKCBBJiBh ICkgeyBhLmdldF9hKCk7IH07CnByaXZhdGU6CiAgaW50IGE7Cn07CgpjbGFzcyBCIDogcHVibGlj IEEgewogcHVibGljOgogIGludCBnZXRfYSgpIHsgcmV0dXJuIDA7IH0KICBCKCBpbnQgYSApIDog QSAoIGEgKSB7fQp9OwoKY2xhc3MgQyA6IHB1YmxpYyBCIHsKcHVibGljOgogIEMoIGludCBhICkg OiBCKCAwICksIGIoIGEgKSB7fQogIGludCBnZXRfdmFsKCkgeyByZXR1cm4gZ2V0X2EoIGIgKTsg fQpwcml2YXRlOgogIEIgYjsKfTsKCmludCBtYWluKCl7CiAgZXhpdCgwKTsKfQo=
