Error "index=4 count=3" with LayoutAnimation.easeInEaseOut() on Android

[jer-sen]

On Android, updating a specific (but very simple) component tree after calling LayoutAnimation.easeInEaseOut() leads to an error :

index=4 count=3

Here is a repro : https://snack.expo.io/H1H0AbDZM
Just click 2 times on the top text component to see the app crash.

This bug has been there for several months and is still there with react-native@0.51.0.

Thanks in advance for your help.

Same issue here. Test the template below. Trying to toggle some views using a button.
Throws the error "index=4 count=3" after a few toggles.

import React, { Component } from 'react';

import { 
  View, 
  Text, 
  LayoutAnimation, 
  Button } from 'react-native';


export default class Testing extends Component {
  state = {
    showOthers: false
  }
  componentWillUpdate(){
    LayoutAnimation.easeInEaseOut()
  }
  showOthers = () => {
    this.setState({ showOthers: !this.state.showOthers })
  }
  render() {

    const { showOthers } = this.state

    return (
        <View>

          {showOthers && 
            <View>
              <Text>One</Text>
              <Text>Two</Text>
            </View>
          }
          
          <Text>Three</Text>
          <Text>Four</Text>

          {showOthers && 
            <Text>Five</Text>
          }

          <Button onPress={this.showOthers} title={showOthers ? 'Hide Others' : 'Show Others' } />

      </View>
    );
  }
}

Using:

"react": "16.2.0",
"react-native": "0.53.0",

I'm facing the same problem.
