            Bug ID: 59978
           Summary: C++11 Non-Type-Template-Parameter Pack Expansion not
                    working according to standard
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

minimal-example source file from the description

In the code below "Ints..." should expand to "1, 2" and therefore correctly
match the signature for "testFunc", but g++ 4.8.2 complains about
"too few arguments to function âvoid testFunc(int, int)â"

static void testFunc(int i1, int i2) {
    (void)i1;
    (void)i2;
}

template <int... Ints> void wrapper() {
    testFunc(Ints...);
}

int main(int, char *[]) {
    wrapper<1, 2>();    
    return 0;
}

Command line: g++ -std=c++11 -Wall -Wextra non-type-template-parameter-pack.cpp

Tested with g++ 4.8.2 on ArchLinux (i686):
g++ -v
Using built-in specs.

gcc version 4.8.2 20131219 (prerelease) (GCC) 

GCC from Git-master from 2014/01/28 produces the same error message.

The code compiles fine on clang (3.3 and 3.4)
