hi john,

first, i did not clip anything except this line:
/home/.../unsigned.cpp: In function âint main()â:

which is in my opinion not really interesting..

well, u1 is defined as follows:

rdf::ustring u1 = "Hello";
u1 += "  ";

it's simply a instance of the rdf::unsigned_string class.. sorry that i forgot to metion that.

thanks for the hint.. i may have noticed it by the time the program had compiled. i tried out
so many things the last weeks, it may have happend that this senseless stuff appeared by
some batch modification.

thank you!
