Application.Unload crashes with the 4.x scripting runtime




Priority: 3Not yet prioritized for a release


Severity: 1Crash, freeze, data loss, work stops

To reproduce:
1. Build & run to an android device
2. Press the "Crash" button
3. Notice that the app crashes (can be done by using Android Device Monitor or logcat). There will be a log similar to: 07-16 12:08:24.113: E/InputDispatcher(1145): channel '9ce9451 com.Company.Pauser/com.unity3d.player.UnityPlayerActivity (server)' ~ Channel is unrecoverably broken and will be disposed!

This crash happens when trying to call a mono destructor when mono has already been unloaded. This destructor was passed when calling pthread_key_create and it crashes when trying to call it on pthread_key_clean_all.
