[GCKDatabase initWithEmpty:inMemory:runtimeConfiguration:] crash on iOS < 11

[piterwilson]

Hello,

I have a cryptic crash happening on initialization of my app which includes the Chromecast SDK. The crash happens intermediately after launch and only on iOS < 11 (10 and 9 confirmed)

The class involved is GCKDatabase which looks like an internal class. It is private and has no documentation so debugging is extremely difficult.

The application crashes in an Enterprise distribution only and doesn't crash when exported locally using XCode.

What possible causes must i consider?

Thanks
