ios: 2 function calls on the same interface, one working... the other function call doing literally nothing

Hi,

we have a big problem when using mono on IOs.

We have an Interface

 public Interface Inter
 {
  void CallA(int x);
  void CallB(short x);
 }.

We have a mono exe on IOS that implements this interface. The Interface is part of a dll. when the Dll calls

  interface.CallA(0)

the call is received correctly.

when it calls

  interface.CallB(0)

Nothing happens.

We have log output before and after each calls... the function is called but nothing happens.

If we compile the dll code in the same exe everything works.

on all other platforms ( mac, windows) everything works. It even works inside the IPhone Simulator....

We disabled code stripping and eliminate dead code in xcode.

We would be very happy if anyone has an idea...

I guess the issue is an AOT or JIT problem.

We were allready talking with some monotouch guys.. they said we should try to disable llvm .. this is not possible in unity, is it?

Thanks in advance...
