ZASM Output Error

I'm trying to cross-associate ZScript functions, to ZASM, for the purpose of documentation, and while running qa simple test, compiling and ticking 'Output ZASM to allegro.log', the output was garbage:

�
H€Š*y–nit
�

This was produced by placing into the compiler buffer:

global script init{
     void(run){
         Sin(30);
         Rand(40);
     }
}

Compile + Output ZASM.

It seems that the declaration of global script init, on its own, produced corrupted assembly.

I should be seeing pure ASCII output, with ASM instructions. This looks more like binary code represented as ASCII text... What exactly is happening here?

Further, despite making a fully new quest, and entering only one global active script into the buffer, then compiling, in the ZASM output, I see these lines:

GhostZHActiveScript
GhostZHActiveScript
�
H€Š*y–nit

How is GhostZHActiveScript being retained, and stored in a log file, for a quest with no active script, and no calls to Ghost.zh at all?

Is this something Saffith added to ZASM?
