gv 3.6.6 not rendering fully

[Andrew P. Billyard]

Hi,

I've included a small postscript which several postscript interpreters seems to handle fine, but ghostview (gv) doesn't.  Unfortunately, gv is my favourite.  There are supposed to be two blue circles with red triangles inside them, but only one of these get rendered...and the cursor is displaying "busy" almost as if gv hasn't finished rendering.  Any suggestions would be fine.  

Sincerely,
Andrew
