Bug ID: 117993
Summary: inherited variables and functions not found in nested
class
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: conradsand.arma at gmail dot com
Target Milestone: ---
Created attachment 59831

short program with templated and nested classes
Using the attached program, GCC 15 20241208 complains with:
gcc15bug.cpp: In member function ‘void B<T>::C<n>::bar()’:
gcc15bug.cpp:23:13: error: ‘struct B<T>::C<n>’ has no member named ‘foo’
[-Wtemplate-body]
23 | (*this).foo();
| ^~~
gcc15bug.cpp:24:13: error: ‘struct B<T>::C<n>’ has no member named ‘x’
[-Wtemplate-body]
24 | (*this).x = T(3);
Class C inherits the member function foo() and variable x from class A via
class B, so this should work.
GCC 14.2 and clang 18.1.8 (both from Fedora 40) compile this program without
problems, suggesting this is a regression in GCC 15.
