--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Seems to have been fixed by r189640 for GCC 4.8
* pt.c (instantiate_decl): Don't recheck substitutions.
At that revision we reject the testcase with this error:
45011.cc:9:17: error: template-id ‘function<C>’ for ‘void function(int)’ does
not match any template declaration
template<> void function<C>(int parameter) {
^
45011.cc: In function ‘int main()’:
45011.cc:13:16: error: no matching function for call to ‘function(int)’
function<C>(0);
^
45011.cc:13:16: note: candidate is:
45011.cc:6:27: note: template<class T> void function(typename T::Private)
template<typename T> void function(typename T::Private);
^
45011.cc: In function ‘void function(typename T::Private) [with T = C; typename
T::Private = int]’:
45011.cc:3:15: error: ‘typedef int C::Private’ is private
typedef int Private;
^
45011.cc:6:27: error: within this context
template<typename T> void function(typename T::Private);
^
The error changed at r195779
re PR c++/56208 (Some classic sfinae cases fail to work due to access
problems)
PR c++/56208
* pt.c (fn_type_unification): Discard any access checks from
substituting explicit args.
Since then we print:
45011.cc:9:17: error: template-id ‘function<C>’ for ‘void function(int)’ does
not match any template declaration
template<> void function<C>(int parameter) {
^
And the error is similar today:
45011.cc:9:17: error: template-id 'function<C>' for 'void function(int)' does
not match any template declaration
9 | template<> void function<C>(int parameter) {
| ^~~~~~~~~~~
45011.cc:6:27: note: candidate is: 'template<class T> void function(typename
T::Private)'
6 | template<typename T> void function(typename T::Private);
| ^~~~~~~~
