Crash on iOS with RN 0.76.x and reanimated 3.16.7 after upgrade

[fjmorant]

Description

App is randomly crashing on launch and getting issue in iOS using old architecture, this has happened since we upgrade it React Native to version 0.76.5 and reanimated to 3.16.7. It is difficult to determine the reason of it because it is very random but we can check the stacktraces.

Steps to reproduce

At launch of the app we are getting these stack traces all related to Hermes GC:

Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

[fjmorant]

It seems from the stacktraces as if it was an excessive consumption or memory by animations due to some sort of too frequent operation

Maybe these cherry picks can help to this crash https://github.com/software-mansion/react-native-reanimated/issues/6996

We're seeing a crash that looks identical in our app as well. It started after upgrading several of our dependencies, including Reanimated from 3.6.3 to 3.16.7 and React-Native from 0.72.10 -> 0.76.6. Hoping that you're correct and the next release fixes the crashes.

I'm on 3.17.5 and on 0.76.9 of react-native. That release didn't fix the problem for me :(. Any news on this matter?

@MarlonAEC Hi, have you tried upgrading react-native to the latest version?

[hasanalicansu]

@tomekzaw hello,

Did you try on last react native version (0.79.x). I tried and i encountered crash.

• new arch disabled
• react-native-reanimated: 3.17.5
• react-native: 0.79.2

[MarlonAEC]

I did tried @tomekzaw actually I'm struggling with the update. I found several issues while upgrading, the most annoying one is this:

error: no such module 'XXX'

error: failed to verify module interface of 'XXX' due to the errors above; the textual interface may be broken by project issues or a compiler bug

where XXX are several modules, to mention a few:

'React-Codegen',
'FirebaseSharedSwift',
'react-native-didomi',
'PromisesSwift',
'FBLPromises',
'FirebaseRemoteConfigInterop',
'FirebaseCoreInternal',
'FirebaseCore',
'FirebaseRemoteConfig',
'FirebaseABTesting',
'FirebaseInstallations',
'FirebaseSessions',
'FirebaseCoreExtension',
'AppAuth'

But anyways, I need to figure out the update first and make it work to see if I can replicate the original problem in this version, although as I mentioned in the other issue, I tried 3.17.1 and it worked fine I just landed in another problem which I'm still trying to figure it out

Try updating to, at least, React Native 0.77.0. I believe Xcode 16.3 doesn't play well with versions bellow that. This fixed a similar crash to me.

We are seeing a lot of similar crashes, in fact our Sentry is swarmed with hundreds of different variations of EXC_BAD_ACCESS, big production app. I know that it happens randomly on app launch but I have never seen this happen locally. For us it started happening after we updated Expo from 52 to 53 which in turn prompted an updated of RN from 0.76.2 to 0.79.2 and Reanimated from 3.16.7 to 3.17.4 (among many other updates). Old arch, iOS only. I am not entirely convinced that this is the same issue, but some of our crash logs look very similar.
