My compiler vendor and i disagree over the behavior of the appended
code. I expect the stream extraction to fail setting both the eofbit and
failbit on the second "In1 >> str". The compiled code returns an empty
string in the "else".

I'm not sure i can make a case based on the wording in this section.
Maybe the failbit definition in 27.4.2.1.3 applies.

Can someone help? Is this clearer in the 11/97 standard?

#include <fstream>
#include <sstream>
using namespace std;
string buf("    a    ");

main()
{
  istringstream In1(buf);
  string str;
  In1 >> str;
  // expect and get "a"
  cerr << "\"" << str << "\"" << endl;
  In1 >> str;
  if (!In1)
  {
    // expect failbit and eofbit to be set
    cerr << "fail" << endl;
  }
  else
  {
    // actually get an empty string here
    cerr << "\"" << str << "\"" << endl;
  }
}
