------- Additional Comments From bangerth at dealii dot org  2004-07-28 20:18 -------
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. 
Please submit a full bug report, 
with preprocessed source if appropriate. 
See <URL:http://gcc.gnu.org/bugs.html> for instructions. 
 
This is a regression in 3.3.x against previous versions, but it 
is already fixed in 3.4 and mainline.
