[Bug c++/45603] New: cc1plus crashes in "build_addr_func"

["jobnoorman at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following code crashes cc1plus (tested with 4.3, 4.4 and trunk revision
164022) inside "build_addr_func":

//start code (test.cpp)
template<typename T>
struct Singleton
{
    static T* get()
    {
        static T instance;
        return &instance;
    }

    ~Singleton() {}
};

struct Foo : Singleton<Foo>
{
};

extern "C" int __cxa_guard_acquire()
{
}

void foo()
{
    Foo::get();
}
//end code

It does not crash when you remove ~Singleton or __cxa_guard_acquire.
