This bug was already mostly fixed by the patch for PR17314. This patch continues that by ensuring that where a using decl is used, causing an access failure to a child class because the using decl is private, the compiler correctly points to the using decl as the source of the problem. gcc/cp/ChangeLog: 2021-03-10 Anthony Sharp <anthonysharp15@gmail.com> * semantics.c (get_class_access_diagnostic_decl): New function that examines special cases when a parent class causes a private access failure. (enforce_access): Slightly modified to call function above. gcc/testsuite/ChangeLog: 2021-03-10 Anthony Sharp <anthonysharp15@gmail.com> * g++.dg/cpp1z/using9.C: New using decl test.
