[Bug libstdc++/44441] New: std::getline set failbit in situation when shouldn't

[qwak82 at gmail dot com]

In this code s failbit is set if last line in s is empty (stream ends with
\n\n):
std::istream s;
//s is some kind of input stream like std::istringstream s("\n\n");
while (s.good()) {
 std::string line;
 std::getline(s, line);
}

But also fail bit, this program prints:
line: a  //this is OK, first line
line://this is also OK, second (empty) line
fail bit //eof is set - OK; but fail bit should be set here?

#include 
#include 

int main() {
std::istringstream s("a\n");
while (s.good()) {
 std::string line;
 std::getline(s, line);
 std::cout << "line: " << line << std::endl;
}
if (s.fail()) std::cout << "fail bit";
return 0;
}
