Realm exceptions not caught by try-catch on Android.

I'm using Realm 11.9.0 with ReactNative 0.71.8 and I'm running into problems where I can't catch Realm exceptions. This only happens on Android.

Just for the sake of testing, I passed an empty object to Realm and wrapped that code in try-catch as shown below.

    database.beginTransaction();
    try {
      database.create(User, {}) // This throws exception as we haven't passed an id
      database.commitTransaction();
    } catch (e) {
      database.cancelTransaction();
    }

This code behaves differently on Android and iOS.

On Android, this crashes the app with some errors like Fatal signal 6 (SIGABRT), and the catch block is not executed.

On iOS, this doesn't crash the app and the code in the catch block is executed.

Is this some kind of known limitation of ReactNative and JSI on Android or am I missing something?

It turns out to be an issue with the libc++_shared.so. One of our native dependencies was overriding it which caused Realm to crash.
