Description of problem:
icall.cpp: In function `void SicVal(const T&)':
icall.cpp:26: internal compiler error: in cp_tree_equal, at cp/tree.c:1627


I've reduced the code to the following test case:

struct TfTraits
{
    template <bool B> struct BoolType { static const bool value =
false; };
    template <class T> static T &Hypothetical();
};

struct Sic_Traits
{
    template <class T, bool B> struct _Type { };
};

template <class T, bool B>
class Sic_TypedValHelper
{
public:
    Sic_TypedValHelper(const T &t) : _data(t) { }

private:
    T _data;
};

template <class T>
void SicVal(const T& t)
{
    typedef typename Sic_Traits::_Type<T,
TfTraits::BoolType<(sizeof(foo(TfTraits::Hypothetical<T*>())) ==
sizeof(TfTraits::BoolType<true>))>::value> TypeTraits;
    new Sic_TypedValHelper<T,
!TfTraits::BoolType<(sizeof(foo(TfTraits::Hypothetical<T*>())) ==
sizeof(TfTraits::BoolType<true>))>::value>(t);
}


Version-Release number of selected component (if applicable):
gcc-3.4.1-1

How reproducible:
Always

Steps to Reproduce:
1. Place the above source code in icall.cpp
2. gcc -c icall.cpp
    

Actual Results:  icall.cpp: In function `void SicVal(const T&)':
icall.cpp:26: internal compiler error: in cp_tree_equal, at cp/tree.c:1627


Expected Results:  The code should compile.

Additional info:

This works fine with gcc 3.2 and gcc 3.3.
