[Qt-interest] Problem with QHash and QThread

[Andrei Sebastian Cîmpean]

Hello everybody,

I have stumbled upon a problem that I don't quite understand and I was hoping 
someone can help me get to the bottom of it.
I have a class that inherits QThread. In the header file I have:

inline uint qHash(const QPoint& p)
{
    return qHash(p.x()+p.y());
}
struct Hexagon{
    QPoint center;
    int centerSSD;
    QHash<QPoint,int> points;
};
class HexagonalSearch : public QThread, public BlockMatching
{
    Q_OBJECT
(...)

, with BlockMatching being a simple class that just has some functions preset.
It compiles without any warnings, although I know that's not necessarily a 
condition for no problems.
When I run the app and it gets to part where it has to execute the run() 
function the app crashes. I can't debug using Qt Creator (don't know why it 
freezes at setting breakpoints even after reinstall) but when I run the 
debugger it instantly crashes with the message "The inferior stopped ...." -> 
Segmentation fault, and it displays assembly code with a flag set for a 
compare (cmpq).
I have attached a screenshot with the result.
Any help would be greatly appreciated and would probably save my life.

Thank you for your time and patience,
Andrei Sebastian Cîmpean
