<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The reference bug describes a crash when displaying the "Caution: Driving instructions may be..." message box when guidance is started.
The problem is that a QCheckBox is created on the stack and added to the message box, which adopts it as a child. This is dangerous according to the QObject::~QObject documentation:
Warning: All child objects are deleted. If any of these objects are on the stack or global, sooner or later your program will crash.
This change creates the check box on the heap instead; as a child of the message box, it will be deleted when the message box is deleted.
