C ++ 11 Code :: Blocks GCC crashes when compiling a variational template of dependent member structures

I tested the variadic templating idea in C ++ using Code :: Blocks and when I try to compile it the build fails and says:

'
in dependent_type_p, at cp/pt.c:19367
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://tdm-gcc.tdragon.net/bugs> for instructions.
Process terminated with status 1 (0 minute(s), 1 second(s))

I followed the instructions and filed a bug report, but in the meantime I want to know if I need to fix my code or get a new compiler. The code I wrote is:

#include <iostream>
#include <array>
using namespace std;

struct Foo1
{
    struct init {};
};

struct Foo2 : public Foo1
{
    struct init{};
};

struct Foo3 : public Foo2
{
    struct init{};
};

template <typename... Args>
void Bar(typename Args::init... args)
{
    array<void*, sizeof...(Args) + 2> t = {nullptr, &args..., nullptr};
    for (size_t x = 1; x < sizeof...(Args) + 1; ++x)
        cout << t[x] << endl;
}

int main()
{
    Foo1::init a;
    Foo2::init b;
    Foo3::init c;
    Bar<Foo1, Foo2, Foo3>(a, b, c);
}

      

        
        
        
      

    

It works if I manually deploy Bar

to:

template <typename A, typename B, typename C>
void Bar(typename A::init a, typename B::init b, typename C::init c)
{
    array<void*, 5> t = {nullptr, &a, &b, &c, nullptr};
    for (size_t x = 1; x < 4; ++x)
        cout << t[x] << endl;
}

      

        
        
        
      

    

The error is somehow caused by the variation pattern, but I don't understand it at all. I hesitated to ask because we have to point out the exact problem, but the whole compiler said something like a dependent type.
