Are you able to reproduce with fewer Firebase pods in use to narrow down the scope? In particular, I'm wondering if this crash is dependent upon FirebasePerformance like #486.

[jlaws]

I haven't seen the issue again today, so it may be dependent on receiving corrupt or incomplete data from the server. If/when it starts happening again I will remove Firebase PODs to try and isolate it. Thanks Paul!

@jlaws also, if there are any non-Firebase pods in use that would be helpful too!

Also, its happening again, trying to isolate it to a pod now

[jlaws]

It appears FirebasePerformance is the problematic pod. The problem disappears when FirebasePerformance is no longer part of my project. Luckily I don't really use any of the performance tools (yet) so I will leave it off for now.

[paulb777]

@jlaws Thanks for narrowing it down!

The issue may be an duplicate of #486 which is being fixed in the next FirebasePerformance release. cc: @mikehaney24

[mikehaney24]

We're not sure this is a duplicate issue (though we hope it's fixed next release). So, we're tracking this internally with b/70392677.

[paulb777]

@jlaws Do you still see this with FirebasePerformance 1.1.0?

[jlaws]

Re-enabling the pod, will try it out for our next release and let you know

[jlaws]

Still causing the crash, removed the pod again
