Description

*This has only happened once, I am unable to reproduce and therefore I am uncertain on the steps to reproduce. I was running KS on two devices at the time, only one of the devices crashed. The second device is an iPad Air 2 running 8.2b3* *I can not be certain as to whether this is a regression as I have been unable to reproduce the issue again.* When running KitchenSink I ran into a crash when entering BaseUI->Views->Table Views->Events. I had been running the test for around 2 hours. I simply tapped on 'Events' and the app crashed back to the springboard. There *were* crash logs on device and I have them attached as crash.txt.

Steps To Reproduce

*I am unsure of the steps required to reproduce*

Actual Result

The app crashed, I am unsure as to the reason why

Expected Result

The app should not crash

We tried the KitchenSink app with following environment and observed *crash* in 3 times. But we couldn't define any concrete reproduction step. 3 places where we observed the crash. Crash logs are attached for all 3 scenarios. 1. BaseUI > Views > Table View > Events 2. Controls > Slider > Basic 3. BaseUI > Views > Table View > Events At the 3rd scenario, following console log is observed in Studio.

I can not reproduce this. Logs seem to indicate a segmentation fault which might be related to the crash seen in TIMOB-18249. Resolving this. Please reopen if problem persists
