           Summary: Error: /typecheck in --run--
           Product: Ghostscript
           Version: master
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P4
         Component: PDF Interpreter
        AssignedTo: alex.cherepanov at artifex.com
        ReportedBy: marcos.woehrmann at artifex.com

The customer reports and I've verified that the attached PDF file generates a
Error: /typecheck in --run-- when read by Ghostscript head

Ken did some analysis and found: 

The PDF file contains a Form XObject (47 0 obj) which has no content stream.
This seems (not unreasonably) to confuse the PDF interpreter. If I remove the
/R2 Do from the page content stream so that we don't use the Form XObject, then
the file runs to completion.

Adobe Acrobat X 10.1.0 and Apple Preview 5.0.3 read the file without complaint;
mupdf generates a warning but reads the file correctly.

The command line I'm using:

  bin/gs -sDEVICE=ppmraw -o test.pdf ./DSP773.pdf
