[IL2CPP] System.Array.Copy() corrupts data with IL2CPP

IL2CPP

-

-

Priority: 3Not yet prioritized for a release

-

Severity: 3Secondary functionality broken

When copying arrays using IL2CPP, the results differ from the ones when using Mono compiler.

Steps to reproduce:
1) Open the latest attached project.
2) Build for iOS or Android.
3) Run on a device.
4) Observe the output of System.Array.Copy() on the device screen or in the console (last line).

The last line of output should be
"toBoard: [[null, null, null], [null, null, null], [null, Cross, null]]", however, when built using IL2CPP it reads:
"toBoard: [[null, null, null], [null, null, null], [null, null, null]]"

This does not occur on the Editor or when deployed using Mono2x. This occurs on both iOS and Android.

Reproduced on:
5.6.0a2, 5.5.0b11, 5.4.2p4, 5.3.7f1, 5.2.4f1

Devices tested:
iPhone 7 iOS 10.2
iPad Air 2 iOS 8.1
LG Nexus 6X Android 6.0.1
