QTestLib doesn't recognize NULL pointers?

Ok, this sounds logical.
I'm accessing nothing class-specific in that method. I'm just returning a new QString Object...

QString HelloWorld::hello()
{
    return "Hello World!";
}

QString HelloWorld::hello()
{
    return "Hello World!";
}

To copy to clipboard, switch view to plain text mode 

So... i've just tested it with this:

QString HelloWorld::hello()
{
    _string = "Hello World!";
    return _string;
}

QString HelloWorld::hello()
{
    _string = "Hello World!";
    return _string;
}

To copy to clipboard, switch view to plain text mode 

...while _string is a member of HelloWorld class. And now it crashes, like it should!

Wondering if the compiler is optimizing the return "Hello World"; from the first hello() method out, and that is the reason no crash occures.
Or what other reason there is, why there's no error at runtime...?

Thank you!

No crash occurs because the compiler never tries to dereference "this" when inside the hello() method. If you make that method virtual, it will start crashing.

Ok!
Thanks a lot!
