[Bug c++/16806] New: Internal compiler error: Error reporting routines re-entered.

I don't know what I'm doing with c++ and was trying to get something to compile
when I got an internal compiler error.  Clearly my code is wrong, but still
shouldn't have an internal error.

I was trying to compile the following:

#include <iostream>

template<class T> class myclass {
public: 
        
        template< T > int Get< typename U >();
        
        template<T> int Get<float>() { return 1;}
        template<T> int Get<int>() { return 2;}
};

int main() {
        myclass<int> c;
        std::cerr << c.Get<float> << std::endl;
        return 0;
}       

g++ -Wall specnothing.cpp 
specnothing.cpp:6: error: parse error before `>' token
specnothing.cpp:8: error: template-id `Get<float>' in declaration of primary 
   template
specnothing.cpp:9: error: template-id `Get<int>' in declaration of primary 
   template
specnothing.cpp: In instantiation of `myclass<int>':
specnothing.cpp:13:   instantiated from here
specnothing.cpp:9: error: `template<int <anonymous> > int myclass::Get() [with 
   T <anonymous> = enumerator, T = int]' and `template<int <anonymous> > int 
   myclass::Get() [with T <anonymous> = enumerator, T = int]' cannot be 
   overloaded
specnothing.cpp: In function `int main()':

[Bug c++/16806] [3.3 regression] Internal compiler error: Error reporting routines re-entered.

This code is completely and absolutely broken. However, to my great 
surprise I could even reconstruct the ICE with something that is 
almost valid and should indeed give a single regular error: 
----------------- 
struct X {}; 
void operator << (const X &,int); 
 
template<class T> struct myclass { 
    template<typename> int Get(); 
}; 
 
int main() { 
  X() << myclass<int>().Get<float>; 
}       
------------------------- 
Note that only the parentheses to the call of myclass::get were 
forgotten in this code. Yet, we get: 
 
g/x> /home/bangerth/bin/gcc-3.3.4-pre/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:9: error: no match for 'operator<<' in 'X() <<  
Internal compiler error: Error reporting routines re-entered.

This is a regression in 3.3.x against previous versions, but it 
is already fixed in 3.4 and mainline.

This is even a regression *on* the 3.3 branch, introduced between
gcc 3.3 and gcc 3.3.1.
