No crashes here with roundabouts, too.

I'm using rules like this for every routable way... 
# secondary

highway=secondary  [0x12004 resolution 21-20 continue]
highway=secondary	  [0x11004 resolution 24-22 continue]
highway=secondary & junction=roundabout  \
	[0x0c resolution 24 road_class=2 road_speed=2]
highway=secondary \
	[0x04 resolution 24 road_class=3 road_speed=4]

... and every routable ways is an invisible line with overlay

Xpm="32 1 2 1"
"0 c #FFFFFF"
"1 c none"

BTW: there isn't any special access rule for roundabouts in our style
