Hi, I'm trying to use Marshal.StructureToPtr to convert a structure before sending via a socket to another app. It works in the editor, but crashes on the Marshal.StructureToPtr call in the webplayer.

Heres some example code:

[StructLayout(LayoutKind.Sequential, Pack = 1)]

public struct SENDPOS { public long SendId; public float x,y,z; };

    SENDPOS PlayerPos;
    byte[] arr;
    int len;
    IntPtr ptr;

//(in Start() )

    len = Marshal.SizeOf(PlayerPos);
    arr = new byte[len];
    ptr = Marshal.AllocHGlobal(len);

//in Update()

    Marshal.StructureToPtr( PlayerPos, ptr,false); //<-------- CRASH HERE
    Marshal.Copy(ptr, arr, 0, len);
    ClientSocket.Send(arr, len, SocketFlags.None);

Is marshaling supposed to work in the webplayer, or is this a Unity bug? Or am I doing something wrong in the above code?
