Ice for C++ from ZeroC (http://www.zeroc.com, source code available) doesn't compile anymore with 
GCC 4.0.0 (I also tried with GCC from CVS and the result is the same). It compiled fine with GCC 3.4.2. 

I'm getting an error which looks like the following with 4.0.0:

Main.cpp: In constructor 'IteratorI::IteratorI()':
Main.cpp:31: error: no matching function for call to 'Iterator::Iterator(const void**)'
Main.cpp:6: note: candidates are: Iterator::Iterator()
Main.cpp:6: note:                 Iterator::Iterator(const Iterator&)

I don't understand why it's looking up this constructor, the code doesn't contain any reference to it. I'm 
also getting a segmentation fault of the compiler with similar code (see the code sample below). Here's 
a small test case demonstrating the problem(s):

-----
class Base
{
};

class Iterator : virtual public Base
{
};
bool operator==(const Iterator&, const Iterator&);

class IteratorI : public Iterator
{
};

class Obj
{
    bool operator==(const Obj&) const { return true; }
};

template <typename T>
bool dummy(const Obj& lhs, const Obj& rhs)
{
    const Obj* lhsKey = &lhs;
    const Obj* rhsKey = &rhs;
    return *lhsKey == *rhsKey;
}

int 
main(int argc, char** argv)
{
    // G++ segfault with the following line uncommented
    //Iterator* it1 = new Iterator();

    // error: no matching function for call to 'Iterator::Iterator(const void**)'
    IteratorI* it2 = new IteratorI(); 
}
