Interlocked methods crashing with IL2CPP

Hey,

I currently work on getting our project ready for IL2CPP. So far everything compiles but during runtime all calls of static Interlocked methods crash.

Here are some C# examples:

Code (CSharp):

1. // we get some bottleneck, start next worker
2. var runningCounter = Interlocked.Read(ref this.runningCounter);

or

Code (CSharp):

1. Interlocked.Increment(ref this.runningCounter);

And here's the compiled CPP code:

Code (CSharp):

1. // System.Int64 System.Threading.Interlocked::Increment(System.Int64&)
2. extern "C" int64_t Interlocked_Increment_m18231 (Object_t * __this /* static, unused */, int64_t* ___location, const MethodInfo* method)
3. {
4.     using namespace il2cpp::icalls;
5.     typedef int64_t (*Interlocked_Increment_m18231_ftn) (int64_t*);
6.     return  ((Interlocked_Increment_m18231_ftn)mscorlib::System::Threading::Interlocked::Increment64) (___location);
7. }

And here's the crash error I get:

Any hints on this one? It's totally strange and as I said, every Interlocked call crashes.

 

I have the same error, did you find a solution meanwhile?

 

This has been happening for me too, and it in fact only happens on 32-bit CPUs. May I ask what release you expect this bug to be fixed in? We're running 5.1.2p3.

 

Thanks Josh, looking forward to it.
