[Bug c++/34822] New: Compiler seg fault with incorrect templated static member variable initialization

["wsf at fultondesigns dot co dot uk" <gcc-bugzilla@gcc.gnu.org>]

Testcase (runme.cxx):

template <typename KernelPixelT>
struct DiffImContainer {
   int id;
   static short xyz;
};
template <typename KernelPixelT> short DiffImContainer<double>::xyz = 0;

int main() {
    DiffImContainer<double> d;
    d.id = 20;
    return 0;
}

If
template <typename KernelPixelT> short DiffImContainer<double>::xyz = 0;
is corrected to:
template <typename KernelPixelT> short DiffImContainer<KernelPixelT>::xyz = 0;
then everything is okay.
