That would be me, I didn't realize that it's .o.

Right.  So why is it silent?  Oh, right, because the coverage checking 
code is turned off by #undef.  I remember doing that, I think it was 
something with me not being able to check NOP runs (which were often 
uncovered IIRC).  I don't think I wrote checking just in the CU 
low_pc/high_pc range.  I'll do that and see how it turns out.
