Redux Crashes the app in React Native IOS Release Build

[tradebulls]

We are facing crash in few of our IOS devices in production app having redux in our project. We are using following libraries in our project:

"react-redux": "7.2.5",
"redux": "4.1.1",
"redux-thunk": "2.3.0"
"react-native":"0.63.4"

We tried replicating the same in latest version of react native as well i.e 0.66.1. The issue can be replicated simply by creating a new project and adding redux to it. It works fine in debug mode and crashes on launch in Release mode.

When we comment Provider tag in index.js the app works perfectly fine in debug as well as release build.

Also, this works fine on Android debug and release mode. Only issue is replicating in IOS release build only.

Any help? Thanks in advance

We tried Profile Building the app in Xcode, which helps us with the logs what crashes the app. The logs are as follows:

*** Terminating app due to uncaught exception 'RCTFatalException: Unhandled JS Exception: RangeError: Maximum call stack size exceeded.', reason: 'Unhandled JS Exception: RangeError: Maximum call stack size exceeded., stack:

If we comment Provider tag in index.js then everything works fine. Please help

I'm afraid that we have no way of knowing what's going on in your app, and no way of debugging something that's going on in React Native like that. Sorry :(

@tradebulls same issue here. Did you find the cause or any fix for that?

@tradebulls @halaei Facing the same issue here, were you able to find any solution?

Yes. Take a look at my comment: facebook/react-native#32672 (comment)
You probably need to split some javascript file with +500 exports in it, in our case a file in which we used to place all the action types.

Without a reproduction we couldn't even try to start looking.
