Description Marcos H. Woehrmann 2012-04-05 21:13:32 UTC
The customer reports and I've verified that the attached PDF file generates a "Error: /typecheck in --run--" error when read by Ghostscript.  The customer is using 9.01 but earlier and later versions that I tried fail in the same way.  Apple Preview, Adobe Acrobat, and mu all read the file without problem.

The command line I'm using:

  bin/gs -sDEVICE=ppmraw -o test.ppm ./E030112_0000105765.pdf

The file has an xref entry that points to a wrong object.
Ghostscript detects this, tries to rebuild the xref but cannot
do this for the files with object streams.

The file runs to completion with -dNoVerifyXref option.

As a quick fix I'll disable xref verification for the files with object streams.
We need to consider extending xref rebuilding code to support object streams.
Comment 3 Alex Cherepanov 2012-04-24 21:53:47 UTC
Don't verify stream xref table because we cannot repair PDF files with
new object format. Such verification only increases the chance that the
file fails.

A patch that does this has been committed as:
