Hi, i have a crash received in my Firebase Crashlytics. I couldn't figure out the root cause of the issue. Could anyone please help me with it.

Here is the complete crash report.
Consider the backtrace of your crashing thread:

Frames 10 through 3 are Security framework code being called by XPC to handle a reply from the trust daemon (trustd). Frame 3 is the interesting one. It seems to be parsing a certificate that came back from the daemon. There are two possibilities here:
-
The trust daemon send a completely bogus response that crashed the parser.
-
Something else within your process is causing this problem.
I suspect it’s the latter. Given that frame 2 is a memory management call, I suspect that something in your process is corrupting memory and this code is just an innocent bystander.
My advice is that you run your app with the standard memory debugging tools to see if you can make this problem reproduce locally.
