QCoreApplication::processEvents "Received a SIGABRT: Aborted"

[hfrmobile]

On a Linux embedded system I get a "Received a SIGABRT: Aborted" when calling QCoreApplication::processEvents().

QString WlanDevice::execProcess(const QString &prog, const QString &arg)
{
	if (_scriptRunning)
	{
		while (_scriptRunning)
		{
			QCoreApplication::processEvents(QEventLoop::AllEvents, 500);
		}
	}

	_scriptRunning = true;

	QString workingDirectory("/usr/local/bin");
	QStringList arguments = arg.split(" ");
	int timeout = 2000; // 2s

	_scriptRunner = new ScriptRunner(prog, arguments, workingDirectory, timeout);
	connect(_scriptRunner, SIGNAL(scriptOutput(QString)), this, SLOT(onScriptOutput(QString)));
	_scriptRunner->start();

	while (_scriptRunning)
	{
		// ****TODO: "Received a SIGABRT: Aborted"
		QCoreApplication::processEvents(QEventLoop::AllEvents, 100);
	}

	return _scriptOutput;
}

When calling the script itself on the shell it works.
Receiving the SIGABRT the very first time when entering the while loop.

Using Qt 4.8.7 on a Linux embedded board.
