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.
