NotSupportedException get_HasShutdownStarted - "This icall is not supported by il2cpp

Hi,

I'm getting the following exception from my iOS App:


NotSupportedException: /Users/builduser/buildslave/unity/build/External/il2cpp/il2cpp/libil2cpp/icalls/mscorlib/System/Environment.cpp(166) : Unsupported internal call for IL2CPP:Environment::get_HasShutdownStarted - "This icall is not supported by il2cpp

This is the C# stackstrace that I have:

System.Threading.ThreadPoolWorkQueueThreadLocals.Finalize () (at <00000000000000000000000000000000>:0)...
