[Bug c++/24791] New: ICE on invalid instantiation of template's static member

[michael dot haubenwallner at salomon dot at]

tracked down sample is:

$ cat xx.cc

template < int I >
struct A
{
        int get_val() const;

        static int val_;
};

template< int I >
int A<I>::get_val() const
{
        return val_;
}

template< int I >    // this is invalid: works with "template <>"
int A<0>::val_(0);

// must instantiate to get ICE
template class A<0>;


$ g++ -v
