Thomas and All,
A follow up: submitted as a tracker defect: http://trac.osgeo.org/mapserver/ticket/3729
The test map file is:
MAP
OUTPUTFORMAT
NAME 'pnga'
MIMETYPE 'image/pnga'
DRIVER 'AGG/PNG'
EXTENSION 'png'
IMAGEMODE 'RGBA'
TRANSPARENT TRUE
FORMATOPTION 'INTERLACE=OFF'
END
STATUS ON
SIZE 954 589
EXTENT 0 0 954 589
RESOLUTION 72
IMAGECOLOR 255 255 255
symbol
name 'circle' filled true type ellipse points 0 0 1 1 end
end
LAYER
NAME 'single line'
STATUS ON
TYPE LINE
feature points 10 10 950 580 end end
CLASS
style
symbol 'circle'
size 20
color 255 255 0
outlinecolor 255 0 0
end
style
width 1
color 0 0 255
end
end
END # end of layer 'single line'
END # end of MAP
The above map file works as desired under 5.6 and demonstrates the problem under 5.7/6.0.

Thomas,
Thanks yet again. I tried your suggestion and it looks quite nice.
If I may, a related question: is there a change in behavior in use of symbols? I'm fairly certain that the MapServer tutorial example worked under 5.6.3, as did my use of the "tie" symbol. The motivation here is to tease out a potential bug in Mapserver 6.0.0-beta1.

for a tie symbol you should specify a (negative) GAP.
something like:
http://www2.terriscope.fr/geocache/wms?LAYERS=osm&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fjpeg&SRS=epsg%3A4326&BBOX=1.34033203125,43.76953125,1.3623046875,43.79150390625&WIDTH=256&HEIGHT=256
is obtained with
SYMBOL
NAME "rail"
TYPE TRUETYPE
FONT sc
CHARACTER '|'
GAP -3
END
...
STYLE
WIDTH 2
OUTLINEWIDTH 1
OUTLINECOLOR "#555554"
COLOR "#ffffff"
END
STYLE
SYMBOL rail
SIZE 5
COLOR "#555554"
END

I tried several other symbols; I used the "circle" as an example because it also worked in the past and is used in the MapServer "Introduction to MapServer", section 2.4.3, "CLASS and STYLE objects".
