[REQUIRED] Step 1: Describe your environment

• Xcode version:13.2.1
• Firebase SDK version:8.13.0
• Installation method: CocoaPods
• Firebase Component: (Core, Database, Firestore, Messaging, Storage, etc)
• Target platform(s): iOS

[REQUIRED] Step 2: Describe the problem

Steps to reproduce:

App was crashed on updating data on firestore document while the app is in background state.

Here is the log:- Path = users.16823, Data = { "current_location" = "<FIRGeoPoint: (31.132658, -89.431470)>"; "location_updated_at" = ""; }

Relevant Code:

let data = [
            "current_location" :  GeoPoint(latitude:31.132658, longitude: -89.431470),
            "location_updated_at" : Timestamp(date: Date())
        ]
Firestore.firestore().collection("users")
            .document(16823)
            .setData(data, merge: true)

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

It looks like the crash is happening while allocating heap memory for the shared_ptr in MutableDocument:

https://github.com/firebase/firebase-ios-sdk/blob/aefb2a469b012f06d2761efbb79a25c21b0b82ad/Firestore/core/src/model/mutable_document.h#L239

The presence of malloc_zone_error in the stack trace suggests heap corruption (according to an internet search). I don't see anything obvious in the stack trace that points to a root cause.

Are you able to reproduce while running your app with address sanitizer or malloc guard?

I'm not sure how to proceed without more information though. Is there any more context you can provide? A reproducible app would be the best, but I understand that may not be possible.

Hey @sspogra. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

Since there haven't been any recent updates here, I am going to close this issue.

@sspogra if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.
