Confirmed, here is a smaller testcase: 
----------- 
template<typename> void fun(int); 
template<typename> void fun(int = 0) {}  
 
int main()  
{ fun(); } 
----------- 
 
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:10: error: no matching function for call to `fun()' 
 
However, we get this from icc: 
g/x> icc -Xc -ansi x.cc 
x.cc(2): warning #845: specifying a default argument when redeclaring an 
unreferenced function template is nonstandard 
  template<typename> void fun(int = 0) {}  
                          ^ 
 
x.cc(5): error: no instance of function template "fun" matches the argument 
list 
  { fun(); } 
    ^ 
 
compilation aborted for x.cc (code 2) 
 
 
So it seems that this is wrong code. Someone will have to look up the exact 
text in the standard though. I find it odd that this only applies to  
templates, not to non-template functions.
