[Mobile] Crash in "resize_initialized() [inlined] Construct at ConstructorUtility.h" using AssetBundle.LoadAssetAsync

Mobile

-

Reproduction steps:
1. Open the attached "CrashTest.zip" project.
2. Change the Platform to iOS or Android.
3. Click "AssetBundle > Builds" in the menu bar.
4. Build and run the project on a device.

Actual behavior:
- The application will crash before reaching 500 "TR=" counter (~ 5 - 120 mins).

Call stacks (may vary on each crash):

Reproduced with:
2018.3.12f1, 2019.1.0b10;
iPad Mini 4 iOS 11.4,
iPad Air 2 iOS 11.0.3,
VLNQA00218, Samsung Galaxy Note9 (SM-N960U), Android 8.1.0, CPU: Snapdragon 845 SDM845, GPU: Adreno (TM) 630,

VLNQA00010, Samsung Galaxy S8 (SM-G950U), Android 7.0, CPU: Snapdragon 835 MSM8998, GPU: Adreno (TM) 540

Notes:
- Readme.txt file Overview part in the project folder explains how the application works in details.
- Call stacks may vary.
- Full call stacks attached in the edit below.
- 2017.4 is untestable: crashes with unrelated call stack on application launch.
- The project doesn't work properly with 2019.2.
