Here's a redux: 
--------------------- 
namespace io { 
  template <typename> int foo(); 
} 
 
using namespace io; 
 
template<> int foo<int>(); 
 
int a = foo<int>(); 
------------------- 
 
g/x> /home/bangerth/bin/gcc-3.5-pre/bin/c++ -c x.cc 
x.cc:9: internal compiler error: in write_unscoped_name, at cp/mangle.c:832 
Please submit a full bug report, 
with preprocessed source if appropriate. 
See <URL:http://gcc.gnu.org/bugs.html> for instructions. 
 
The code is invalid, though: you can't declare the existence of a 
specialization of foo() in global namespace without declaring the 
existence of a general template first. It does not correspond 
to the general template in namespace io.
