Node: 6.6.0
Yarn: 0.19.1
npm: 3.10.3
Watchman: 4.3.0
Xcode: Xcode 9.0.1 Build version 9A1004

Steps to Reproduce

Add this function:

export async function measureView(measureFunc: (callback: MeasureOnSuccessCallback) => void): Promise<MeasureView | null> {
    return new Promise<MeasureView | null>((resolve, reject) => {
        try {
            measureFunc((x: number,
                         y: number,
                         width: number,
                         height: number,
                         pageX: number,
                         pageY: number) => {
                resolve({x, y, width, height, pageX, pageY});
            });
        } catch (err) {
            reject(err);
        }
    })
}

Add the call:
let res = await measureView(this.refs[``].measure.bind(this));

-- ON DEBUG --

1. react-native run-android or ios => WORKS AS EXPECTED.
   -- ON RELEASE --
2. Create release build:

• cd android && ./gradlew assembleRelease => install on a android device (on emulator just drag the apk).
• For ios, create release, Upload to testFlight.

3. The app crashes:
