Bug #: 53211
Summary: range-based 'for' expression of type 'const int []'
has incomplete type
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: i.nix...@gmail.com
This code compiles successfully:
#include <iostream>
template<typename... Args>
void func(Args... ) {
const int arr[] = {1,2,3,4}; // !!!!!!!!!!!!!!!!!!!!!
for (auto it: arr) {
std::cout << it << std::endl;
}
}
int main() {
func(1,2,3,4);
}

But if I change the initialization way of 'arr' like this, I get the following
error:
#include <iostream>
template<typename... Args>
void func(Args... args) {
const int arr[] = {args...}; // !!!!!!!!!!!!!!!!!!!!!
for (auto it: arr) {
std::cout << it << std::endl;
}
}
int main() {
func(1,2,3,4);
}
