QThread crashes on exit

[wysota]

In this case the threads are declared as member variables on the stack, so the threads can't be uninitialized pointers.

Sure they can.

The other thing is I wonder how a private Qt-class variable is not initialized ...

Probably because it was deleted or has not been initialized yet. Or... you have stack corruption.

Thanks again, everyone for your help.

This solved the problem:

UDPThread::~UDPThread()
{
    exit();
    while( this->isRunning() == true ) {
 
    }
 
}

UDPThread::~UDPThread()
{
    exit();
    while( this->isRunning() == true ) {

    }

}

To copy to clipboard, switch view to plain text mode 

My assumption was exit() didn't return until the thread was finished running, but it keeps going.

It looks like exit() stops the event loop and then stops the run() a bit later.

try to use "native" methods of QThread

UDPThread::~UDPThread()
{
	if (isRunning()) {
		quit();
		wait();
	}
}

UDPThread::~UDPThread()
{
	if (isRunning()) {
		quit();
		wait();
	}
}

Oh, right.

I was trying to use the intellisense thing to quickly see what methods were available.

I will change it.
