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+)
