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

Hah. It looks like there are several slightly different problems at play here.
Apparently I just fixed one of them, which I was the one I narrowed in the
reduced test case above.
Then I forgot to try my fix on the initial test case attached to the bug. I
only tried on the reduced test case. Sorry about that.

Here is, I think, a reduced test case for this particular issue:

struct A
{
    static const int i = 1;
    typedef int TI;
};

template<class T0>
struct S0
{
    int i;
};

template<class _T, int>
struct S1
{
    typedef _T T;
    typedef typename T::TI TTI;
    typedef S0<TTI> TT0;
};

template<class T>
void
foo(const T&)
{
    typedef typename T::TI TTI;
    typedef S0<TTI> TT1;
}

int   
main()
{
    A a;
    foo (a);
}


I am currently testing a patch and this time I tested it first on the initial
testcase :-)
