defect in STL string

[cheryl <cheryl at col dot hp dot com>]

I found a possible defect in the STL <string> template.

gcc version 2.95.2
running on HP-UX 10.2
>g++ -o tstring tstring.cxx
>tstring
stream: one two three
s3 != 'three'
s3: 'three'
s3.length(): '6'

The problem is the length of the string s3 is really 5
not 6 so the comparison fails.  I've never submitted a
gnu bug so I'm not sure what the procedure is for finding
out the status of this bug.  Any info you could give me
would be greatly appreciated.

---------  tstring.cxx -------------

#include <strstream.h>
#include <string>

int main()
{
	string s1 = string();
	string s2 = "one two";
	string s3 = " three";
	
	strstream stream;
	stream << s1 << s2 << s3 << ends;
	cout << "stream: " << stream.str() << "\n";

	stream >> s1 >> s2 >> s3;
	if (s1 != "one")    cout << "s1 != 'one'\n";    // succeeds
	if (s2 != "two")    cout << "s2 != 'two'\n";    // succeeds
	if (s3 != "three")  cout << "s3 != 'three'\n";  // fails
	cout << "s3: '" << s3 << "'\n";
	cout << "s3.length(): '" << s3.length() << "'\n";
