Marshal.PtrToStructure in iPhone makes error.

Hi!

I have been working with it for over 3 days.

[StructLayout(LayoutKind.Sequential, Pack = 1)] public class Header { public ushort psize; public ushort cmd; public uint sequenceNum; }

IntPtr p = GetDataFromNative(); Header h = new Header();

h = (Header)Marshal.PtrToStructure(p, typeof(Header));

Marshal.PtrToStructure makes following error. Unhandled Exception: System.ExecutionEngineException: Attempting to JIT compile method '(wrapper unknown) Header:StructureToPtr (object,intptr,bool)' while running with --aot-only.)

How can I solve that problem ? Please Help me...

Best Regards, Adam.
