`### [REQUIRED] Step 2: Describe the problem

When I turn on address sanitizer for my builds, I see the following crash with my calls to addSnapshotListener()

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.

Thank you for the report. It looks like this issue should be fixed by #8610. Can you please try out the fix from that PR and see if it resolves the error you're seeing? If using CocoaPods, you could get the Firestore pod from GitHub:

pod 'Firebase/Firestore', :git => 'https://github.com/firebase-ios-sdk/firebase-ios-sdk.git', :branch => 'ehsann/fix-remote-doc-cache'

(you would have to add the same :git and :branch attributes for any other Firebase pods you're using)

Alternatively, given that the fix is small, you could just apply the patch manually.

@var-const When I try to install using CocoaPods via GitHub, I get the following error:

Looks like there was a typo in the URL posted in the previous comment. Please replace the Git URL with the following:

Also, the ehsann/fix-remote-doc-cache branch no longer exists (it was deleted when the fix was merged). You should just be able to replace it with the commit hash: 4cf4e7c5e2fec340a0008c75b5d5acae5c4bd765

So, with that, can you try this line instead:

pod 'Firebase/Firestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => '4cf4e7c5e2fec340a0008c75b5d5acae5c4bd765'
