Timer.cancel() causes crash on new iOS vm


Please clearly state whether the issue relates to a device/the simulator or
the tools.
If related to a device be sure to specify exactly which device with as much
details as possible.

the problem occurs on new iOS vm

What steps will reproduce the problem?
1. Run this code:

Timer timer = new Timer();
timer.cancel();
timer = null;

2. On iOS simulator do Hardware - Simulate Memory Warning (or wait for garbage 
collection)

What is the expected output? What do you see instead?

I would like to see not crashing app, but it crashes:
