Bug ID: 60605
Summary: incorrect diagosis of default template argument for
function declaration inside class template member
function
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: public at alisdairm dot net
This bug looks looks obscure, but breaks our 'static assert' facility for C++03
compilers (after applying a workaround for the gcc 4.8 unused typedef warning):
template <typename T = int>
struct Foo {
void bar() {
void bug();
}
};
This should simply be declaring 'bug' as a function in the enclosing namespace,
the default template parameter on the class template is irrelevant, 'bug' is
neither a function template nor a member function of a class template.
With g++ -std=c++03 I get:
main.cpp: In member function 'void Foo<T>::bar()':
main.cpp:4:18: error: default template arguments may not be used in function
templates without -std=c++11 or -std=gnu++11
void bug();
^
With g++ -std=c++11 I get:
main.cpp: In member function 'void Foo<T>::bar()':
main.cpp:4:18: error: default argument for template parameter for class
enclosing 'void bug()'
void bug();
^
I am not sure what language rule the C++11 switch thinks it is diagnosing, this
code is accepted by the Clang compiler which I used as a cross-check.
