 Unable to reproduce this -
 
 $ cat > test.cc
 #include <string>
 #include <iostream>
 
 using namespace std;
 
 int main()
 {
   string hi = "Paul";
   cout << "Hello " << hi << endl;
 }
 $ g++ test.cc -o string ; echo $?
 0
 $ g++ test.cc -o string ; echo $?
 0
 
 I suspect you neglected to mention that you had -I. on your command
 line, which is specifically asking for fireworks under these
 conditions.
 
 It would be sensible for cpplib to detect '\177ELF' at the beginning
 of a file and abandon processing it, so as to avoid flooding the
 user's terminal with unhelpful error messages.  (That string cannot
 appear at the beginning of a well-formed C/C++ source file.)  But it
 would still be an error.
