I get EXC_BAD_ACCESS when a ShinobiChart tries to render on my main test device, an iPhone 5 running iOS8b5. The error does not occur when running the same code on other test devices (an iPod Touch 5th gen running iOS7, an iPod Touch 5th gen running iOS8b5, and an iPhone 5S running iOS8b5) or in the iOS8b5 simulator. There's nothing in the iOS 8 release notes about a known bug in Security.framework. The only mentions online of bugs with SecKeyGetBlockSize were from the developers calling the function, so I didn't know how to proceed on that front.
The error occurs every time I use a Shinobi chart (as far as I can tell). The chart data source has all 4 required methods called on it before the error occurs.
Stack trace screenshot:
Sample application that causes the error is here. (I commented out the license key line; that's not the error I'm getting. )
Anybody seen anything like this or have any idea why this might be happening?
