String is zero terminated, but can contain zeroes...

String s; s[s.GetLength()] == 0 is legal operation and is always true.

Thank you for the clarification.

After thinking again I have to admit that there isn't any bug.

When reading the documentation for the first time, I was thinking that

Quote:

void Put(const String& s)
Writes String to the the stream. String can contain zero characters.
s String to write.

means "String may be empty". That was what I wanted to express using the pseudo code "s.GetLength() == 0".

My mistake was that I was trying to build a String with its last character being a '\0' by writing

String str;
str = "xxx\0";

overlooking that the character sequence is actually an array of char which of course sends the trailing '\0' to hell.

Sorry for the hassle.
