Subclassing QAbstractEventDispatcher and implementing unregisterTimer.
I subclassed QAbstractEventDispatcher, lets call it MyEventDispatcher.
I implemented functions:
void registerTimer(int timerId, int interval, QObject *object);
bool unregisterTimer(int timerId);
(There are others, but these two are relevant to this bug).
Now when Qt starts a timer function:
QAbstractEventDispatcher:: registerTimer(int interval, QObject *object); is called.
Which allocates a timerID using QAbstractEventDispatcherPrivate::allocateTimerId();.
Now when the timer is stopped,
MyEventDispatcher::unregisterTimer(int timerId) is called.
From my implementation of the function, since it's not a part of qt source code, I have no way of calling QAbstractEventDispatcherPrivate::releaseTimerId(int timerId).
So, over the course of running my app, it keeps allocating int array of exponentially increasing sizes, and eventually runs out of timerIds to allocate once it reaches 8^8 timerIds.
I already logged a bug report for this: https://bugreports.qt.nokia.com/browse/QTBUG-22794.
But maybe I am missing something very obvious here, or doing something wrong in the implementation of MyEventDispatcher?
