--- Comment #3 from ThePhD <b762...@trbvn.com> ---
This bug is still not fixed by the mentioned revision. When you actually use
the parameter pack, the old error rears its ugly head again. Minimal repro:
template <typename... Args>
void bark( int = 0, Args&&... args ) {}
int main ( int, char*[]) {
bark(); // fine
bark(1); // fine
bark(1, 2); // boom
return 0;
}
Given output:
main.cpp:2:31: error: missing default argument on parameter 'args'
void bark( int = 0, Args&&... args ) {}
^
main.cpp:7:6: note: in instantiation of function template specialization
'bark<int>' requested here
bark(1, 2);
^
1 error generated.
Expected:
Successful compilation.
