ORIGINAL:
public function restoreMatrixTranslate():void {
si32(PrenderDrawCommands.RESTORE_MATRIX_TRANSLATE, offset + 0);
offset += 4;
}
-----------
DECOMPILED:
public function restoreMatrixTranslate() : void
{
si32(offset + 0,4); // si32 argument order is wrong (I have filed another issue with
this)
offset = §§dup().offset + 4; // §§dup shouldn't appear
}

Yes, v 6.x places various §§ instruction over the code.
They should be visible only in some special cases where code could not be decompiled
correctly.
In 5.x or lower, you see "Decompilation error" message and the rest of the method is
discarded in many cases. 6.x solves this by adding §§dup,§§push,§§pop instructions
and proceeding without other commands loss.
Our current goal is to eliminate §§ instructions in the proper code.
I will investigate what is wrong with the sixx instructions, be patient...
I guess it should be correct in current nightly(1206+)
