Bug ID: 106377
Summary: A injected-class-name of a private class is not
accessible in the member of the derived class.
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: xmh970252187 at gmail dot com
Target Milestone: ---
struct B{};
struct C:private B{
};
struct D:C{
void show(){
struct B b;
}
};
This example is accepted by GCC but Clang rejects it. The injected-class-name
of `B` would be accessible as a private member of `C`, which is not accessible
in the member of `D` as per [class.access.base] p4.
Further, [class.access] says
> Access control is applied uniformly to declarations and expressions.
> The interpretation of a given construct is established without regard to access control. If the interpretation established makes use of inaccessible members or base classes, the construct is ill-formed.

Looks like the problem is only with the class/struct key; without the struct
(or class) keyword, GCC correctly rejects it.

I suspect this is the same issue as PR 29040. see bug 29040 comment #2 which
describes basically the same thing I found.
Note ICC warns about this code being done for compability reasons with cfront
too (basically the long history of GCC and even pre-standard C++ has left some
things like this around).

Turns out this is a dup of bug 65520.
