Offending source code:   
//BEGIN SOURCE CODE:   
template <class T>   
struct bar {   
    typedef T INNER_TYPE_DEF;   
};   
   
template<class T>   
void func(){   
    typedef typename bar<T>::INNER_TYPE_DEF LOCAL_TYPE_DEF;   
    LOCAL_TYPE_DEF<T> b;   
}   
   
int main(){ }   
//END SOURCE CODE   
   
Obviously "LOCAL_TYPE_DEF<T>" is nonsensical, I stumbled on this segfault as a   
result of a typo.
