firebase-ios-sdk: App crashes in Release mode while logging App start session event

Description

App works fine in Debug mode but crashes in Release mode upon App launch while logging App start session event. Screenshot 2023-06-06 at 4 56 23 PM

Reproducing the issue

We are observing this issue when using Bazel(https://bazel.build/) build system hence the Demo project is also built using Bazel.

To reproduce.

Clone this repo - https://github.com/sanju-naik/bazel-demo-github , and checkout firebase-sessions-crash-in-opt branch.

Install bazelisk brew install bazelisk
From the cloned repo, cd’into BazelDemo and run bazel run //:BazelDemo_gen to generate project.
open BazelDemo.xcodeproj and build BazelDemo-Release scheme you would notice crash as attached in above screenshot.

@sergiocampama Thanks for isolating it to a reproducible example and testing the proposed fix! I’ll ask the team to review it this week and target it for our next release.

paulb777 on Feb 26, 2024

The problematic source code was introduced in Firebase 10.6.0 so it may work to use an earlier version.

It might be easier to stay on Xcode 15.2 instead though until the fix releases in 10.22.0.

paulb777 on Feb 28, 2024

I tested the linked PR on a locally modified copy of Firebase, and the crash does not occur any more on my repro cases 🚀

thanks for looking into it over the weekend! wish I could send you a peer bonus 😃
