Post-optimisation PR crashing

[chun-baoluo]

Describe the bug
@bghgary As agreed in this PR #297 , I repost bug description here. Basically, after #297 my app crashes on iOS after several seconds. No such problem seems to exist on Android. Also, problem reproduces only on real devices, iOS simulators seems to work alright.

To Reproduce
Steps to reproduce the behavior:

1. Download sample app https://github.com/star-collector/babylon-playground
2. Build and open on real iOS device (I tested on iPhone X)
3. App crashes after 5 seconds or so

Expected behavior
App does not crash.

Screenshots

I noticed in your linked repo application you are using
"@babylonjs/react-native": "0.4.0-alpha.37"

This version of the package is mean to be compatible only up to Babylon.JS version 5.0.0-alpha.50. Can you try again using "0.4.0-alpha.38"?

[chun-baoluo]

Yes, I forgot to change the package.

Crash occurs with both of them. Seems like the problem has nothing to do with #297.

@bghgary I manually built @babylonjs/react-native package with your latest commit b0a9b0a0717d938c5992eb7d1963fcb51b31ad8c and my app still crashes on iOS with the same error.

I got this to repro. @star-collector Do you have a way to set up your repro with a locally built @babylonjs/react-native?

Yes, I can built this package manually from any branch you tell me. If you make changes to BabylonNative submodule, I'll just replace folders and rebuild the package.

@bghgary I manually built @Alex-MSFT #302 PR and it fixed the problem!
