pdf segfault on annotation layer when no style is set

[thomas.bonfort@…]

from the example given a few days ago on the mailing list:
LAYER
 NAME 'copyright'
 TYPE ANNOTATION
 STATUS DEFAULT
 TRANSFORM FALSE # coordinates are in pixels
 FEATURE
   POINTS 10 10 END
 END
 CLASS
   LABEL
     SIZE MEDIUM
     COLOR 0 0 0
     OUTLINECOLOR 255 255 255
     POSITION CR
   END
   TEXT 'Copyright 2005'
 END
END


when outputype is pdf, we get a segfault here on the call to 

msGetMarkerSize(&map->symbolset, &(cachePtr->styles[0]), &marker_width,
&marker_height, layerPtr->scalefactor)

in the function int msDrawLabelCachePDF(imageObj *image, mapObj *map)

(sorry for not giving a patch directly, I'm waiting for the patch to bug 492 to
be commited so I can get back in sync ;-)

solution is to add a test for cachePtr->numstyles so this becomes


/* TO DO: at the moment only checks the bottom style, perhaps should check all
of them */
            if(cachePtr->numstyles==0)
            {
            	 marker_width = marker_height = 1;
            }
            else
             if(msGetMarkerSize(&map->symbolset, &(cachePtr->styles[0]),
&marker_width, &marker_height, layerPtr->scalefactor) != MS_SUCCESS)
	      return(-1);
