QThread crashes on exit

[mhoover]

There is no core dump. How do you enable that again? I'm using RedHat if that matters.

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

I realize there are a lot of people who use QThreads all the time, but I don't think a large portion of the herd is running in my direction (lots of threads containing networking classes). The other thing is I wonder how a private Qt-class variable is not initialized ...

Sure they can.

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 ) {

    }

}

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.
