[Bug c++/42225] [4.5 Regression] GCC 4.5 ICE (segfault) on C++ templated code

[dodji at gcc dot gnu dot org]

------- Comment #3 from dodji at gcc dot gnu dot org  2009-12-01 00:26 -------
A reduced test case seems to be:

~=~
template<class T>
struct A
{
    typedef T I;
};

template<class T, int>
struct B
{   
    typedef T TT;
    typedef typename TT::I TT_I;
    typedef A<TT_I> TA;
};  

template<class T>
void  
foo() 
{
    typedef T TT;
    typedef typename TT::I TT_I;
    typedef A<TT_I> TA;
}

int
main ()
{
    foo<A<int> >();
}
~=~

It ICEs with:
test.cc:27:18:   instantiated from here
test.cc:21:21: internal compiler error: tree check: accessed elt 2 of tree_vec
with 1 elts in tsubst, at cp/pt.c:9823
