Legend works in 4.4, but not in 4.6 and above

Can you post the legend output from each version?

I have an HTML legend template file that works wonderfully in MapServer 4.4
and below.  However when using MapServer 4.6 and above my legend breaks.  I
have thoroughly searched and tested for other possible problems but I have
concluded that the problem must lie somewhere in MapServer.  Either
MapServer 4.6 and above reads HTML Legend template files differently than
older versions, or this is a bug in MapServer 4.6 and above.  MapServer 4.6
and above handle the legend well when the mapfile contains a few layers.
But when the number of layers gets large (~10-15), the legend file's code is
never even entered.  The CGI legend tag in my HTML file is simply skipped.
I have included my template file below.  I am fairly desperate so any
thoughts are helpful.  I would like to move to MapServer 4.8 but need the
legend to work first.  Thanks.
