test app that leaks
I've attached a test app which when you hit a button runs a new task (adds numbers) and upon completion swaps a view. The first time the task is run the app leaks.
I have tried to reproduce this issue with following steps:
1. Run the attached sample project .
2. Open Instruments.
3. Choose leaks.
4. Select device and application.
5. Click to record trace.
I observed that the Leaks is generate. But it does't generate every time.

Yes, I mentioned in the description, it only leaks the first time.
I believe the completion of the task causes the thread to return to the thread pool. If a new thread was spun up to complete the task it would leak every time. I tested this by not allowing the task to complete.
I can't reproduce any leaks with Xamarin.iOS 8.0 and the steps from comment #1.
If you can still reproduce a leak with Xamarin.iOS 8.0, please attach the trace from Instruments and explain exactly the steps that created the trace.
Hi Rolf Bjarne,
I have checked this issue with Xamarin.iOS 8.0, And Now It's not generate any leak.
It is working fine at my end.
We could not duplicate the issue (see comment #4).
If you are still experiencing this issue please provide all the requested information and re-open the bug report. Thanks!
