 Here's what I get with the following:
 
 #include <fstream>
 #include <iostream>
 #include <string>
 
 using namespace std;
 int main(int argc, char** argv)
 {
   ifstream in(argv[1]);
   string line;
   getline(in, line);
   cout << "0: " << line << endl;
   cout << "gcount = " << in.gcount() << endl;
   size_t pos = in.tellg();
   cout << "remember " << pos << endl;
   while (getline(in, line))
   {
     cout << "0: [" << line << ']' << endl;
   }
   in.clear();
   in.seekg(pos, ios::beg);
   cout << "restore " << in.tellg() << endl;
   while (getline(in, line))
   {
     cout << "1: [" << line << ']' << endl;
   }
 }
 
 %COMP.sh "-static" 2259.cpp
 <bkoz@fillmore>
 /mnt/hd/bliss/src.gcc/libstdc++-v3/testsuite                    %a.out 
 0: 
 gcount = 0
 remember 4294967295
 restore -1
 
 
 Again, I ask you to simplify. Please try to narrow down the problem. At
 least provide sample compile lines and invocation lines, and expected
 output?
