Could someone please do me a favour and compile this stuff on his system, then try to run it and give me the console output?

Sortierverfahren.cpp line 23 does something I have never seen happen before, when I try to run the program - and I have not the slightest idea as to what could cause this.
Apparently I somehow broke that STL container. Or my OS. Or my PC. ~~
And I would like to know which one of these three.

Compiled with "g++ -Wall -Wextra -o Test *.cpp".

... Oh, of course, if you see my fault, feel free to tell me about it - I am at the end of my wisdom.
