Bug ID: 87478
Summary: Hidden member function falsely takes part in qualified
name lookup
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Example code, which should be rejected
In the attached example, a base class is defined with a member function
template and a derived class is defined with the same member function template.
Both member function templates have the same parameter list but are SFINAE'd
with exclusive conditions.
However, according to http://eel.is/c++draft/namespace.udecl#1 hidden functions
shall not participate in the name lookup and the base function template is
hidden according to http://eel.is/c++draft/namespace.udecl#15. Therefore, the
example code should be rejected, but it compiles without warnings.
The issue came up on this stackoverflow question:
