Hi folks,

     I have run across a sequence that seems to cause my
PostScript printer to become totally hosed, and I am curious to
know why.  I have a Dataproducts LZR 1260 running PS version
47.0.  When I send this little program, it feeds the paper part
way and then just sits there spinning its wheels indefinitely.

	90 rotate
	72 -72 translate
	4.5 -710 scale
	/Courier findfont 1.65 -1 matrix scale makefont setfont
	1 1 moveto (j) show
	showpage

This is a stripped-down version of a much larger program, and the
bug is in the "scale" line -- I originally had an extra "inch"
operator, and it led to an operand of scale being much too high.
Of course, this program is not at all useful, but it still
strikes me as a bug that the engine goes out to lunch like this.

     Steve
