Can anyone explain why this changes anything?

Can I have a less cryptic explanation.  As far as I can see the change was
to swap two fields in a struct.  I cannot see how that changes anything
other than (invisible) layout.

If you are saying that it is a fenceposts -- count from zero -- I can
blieve it is possible

I was thinking of rewriting this area of code to use a list of used
opcodes rather than a vector of the largest, as typically there are not
that many instruments and it seems clearer to me
