QtCreator - Plain C++ Project Hello World only runs without "endl"

[dartsmil]

Hi all,

I have installed Qt 5.0.1 with QtCreator 2.6.2 on Windows 7 and experience a strange behaviour. When I start a new plain C project, everything works fine (the standard Hello World is printed to the console). However when I start a new plain C++ project, again the Hello World is printed to the console but a new (native Microsoft) window pops up and tells me that myprogramname.exe doesn't work anymore . And what I really don't get is the fact that if I delete the part "<< endl" everythings run without problems!

It seems like Qt is having trouble with endl. When I hover endl with my cursor, it says something like "QTextStream & endl...", whereas hovering cout results in "std::cout". Is this perhaps my problem? Can you replicate my problem on your PC? What can I do to fix this problem?

main.cpp

#include <iostream>
 
using namespace std;
 
int main()
{
    cout << "Hello World!" << endl;
    return 0;
}

#include <iostream>

using namespace std;

int main()
{
    cout << "Hello World!" << endl;
    return 0;
}
