Description Marcos H. Woehrmann 2011-07-20 17:11:23 UTC

The customer reports and I've verified that the attached PDF file generates a Error: /typecheck in --run-- when read by Ghostscript head (467b64692f0b74244fd0bc0748309d05b2f09294).

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

Check for the case, where the modified stream dictionary is missing
/File attribute (probably, because the original stream object was
missing the stream body) and provide an empty stream.
