iOS 9 crashes

[dvshelley]

I'm seeing crashes on iOS 8 and 9. It looks like it is in Apple's libraries that it is crashing. Specifically on this line

    status = SecItemCopyMatching((__bridge CFDictionaryRef)query, NULL);

Here is the trace up to this line of code:

Exception Type: SIGSEGV Exception Codes: SEGV_ACCERR at 0xbbadbeef Crashed Thread: 13

I've only seen this in my crash logs. Unfortunately I can't figure out how to reproduce this on a device.

Can you provide any context to how you are trying to use it? I.e in an extension, in the background etc?

[dvshelley]

I'm calling it from applicationWillResignActive as part of code to determine if a passcode is set/TouchID is on for the device so I will know to back out the launch screen. Otherwise, I'm calling it in a few other places before validating TouchID.

Is it only crashing when you check in applicationWillResignActive: or does it do it in those other places too?
