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 Reporter: aemseemann at gmail dot com Created attachment 31976 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31976&action=edit 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 ‘void testFunc(int, int)’" 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.
