Problem with Macro

[GoogleCodeExporter]

Hello.

I'm trying to port my haXe library ( http://www.blooddy.by ) to apparat.

I have a problem with a macro. I get an exception:

I'm compiling swc using tdsi.
The error occurs only with this class:

I cleaned my swc and received a new exception:

Working on the stack overflow error. For some reason 2.8.1 compiler did not 
complain about incorrect @tailrec annotation.

Think i'm stuck with the same issue (Stack Overflow / RC9)...
In case it matters, our Macro looks like this:

public class MemoryMacro extends Macro
    {
        public static function readU32(address:uint, result:int):void {
            result = Memory.readUnsignedByte(address++);
            if ((result & 0x00000080)) {
                result = result & 0x0000007f | Memory.readUnsignedByte(address++) << 7;
                if ((result & 0x00004000)) {
                    result = result & 0x00003fff | Memory.readUnsignedByte(address++) << 14;
                    if ((result & 0x00200000)) {
                        result = result & 0x001fffff | Memory.readUnsignedByte(address++) << 21;
                        if ((result & 0x10000000)) {
                            result = result & 0x0fffffff | Memory.readUnsignedByte(address++) << 28;
                        }
                    }
                }
            }
        }

• Changed state: Duplicate

[GoogleCodeExporter]

Normally the tailrec is fixed in the source for apparat.bytecode.Bytecode.loop .
The one still left is in BytecodeEncoder/Decoder as Joa state.
