Istreambuf_iterator usage with Studio 11

Question

I am trying upgrade some code that is running with Studio 8 to Studio 11 compiler. It uses the Rogue Wave Std C++ library (libCstd).
The code looks like this:
ofstream outStr("Out");
ifstream inStr("in");
if (inStr.peek() != EOF) {
     copy((istreambuf_iterator<char>(inStr)),
     istreambuf_iterator<char>(),
     ostreambuf_iterator<char>(outStr));
When I build this it gives an error:
Undefined first referenced
symbol in file
char std::istreambuf_iterator<char,std::char_traits<char> >::proxy::operator*()
What is the problem and how to fix this?
Thanks

This is the source file:
#include <fstream>
#include <algorithm>
using namespace std;
int main(int argc, char** argv) {
  ofstream outStr("outFile");
  ifstream inStr("inFile"); 
  if(outStr) {  
       if (inStr.peek() != EOF) {
      copy((istreambuf_iterator<char>(inStr)),
         istreambuf_iterator<char>(),
         ostreambuf_iterator<char>(outStr));           
  return 0;
This is the compile command:
CC -I/s11/SUNWspro/prod/include/CC/Cstd  -g -lCstd isbftest.cpp This is the error I get:
Undefined first referenced
symbol in file
char std::istreambuf_iterator<char,std::char_traits<char> >::proxy::operator*() isbftest.o
Interestingly, the code compiles and works if the -g flag is removed from the compile command.
Thanks.
