+Subject: [PATCH] GhostPDF + GS - fix PDFFitPage with square MediaBox
+
+Bug #705849 "New PDF interpreter errors out with PDFFitPage"
+
+If the input PDF file had square media then we would correctly decide
+we did not need to rotate the media for a better fit, but we left the
+values we would normally use to calculate if rotation was required on
+the operand stack, resulting in an error.
+
+Pop the unused values.
