[Bug c++/33964] New: internal compiler error: in dependent_type_p, at cp/pt.c:15319 (vararg templates)

[eric dot niebler at gmail dot com]

I'm not sure if the following should compile or not, but it certainly should
ICE the compiler. Latest gcc from SVN with vararg template patches from Doug
Gregor. Build with -std=c++0x.

Doug, no rush on this one. Just logging it for posterity.

template<typename ... Args>
struct foo
{
    static bool const value = true;
};

template<typename ... Args>
struct foo< typename Args::is_applied... >
{
    static bool const value = false;
};

struct not_applied { typedef void is_applied; };
struct applied { typedef applied is_applied; };

int main()
{
    foo<applied, applied> i;
}
