Description Marcos H. Woehrmann 2008-02-14 14:22:11 UTC
The customer reports and I've verified that the attached PDF file produces an
error when read by Ghostscript (customer is using 8.61, but head (r8526) also
fails).  The error message in the summary is from 8.54, more recent versions
report the less informative "/undefined in --run--".

The command line I'm using for testing:

  bin/gs -sDEVICE=ppmraw -o test.ppm ./5957-64.pdf

Acrobat Reader 8.0 and evince can read the file without problem.

Here's the complete output using gs8.61:

This is yet another case of a TrueType font without a cmap table.
We need to discuss what to do with such fonts.

simplified sample file

This PDF file exercises a TrueType font without a cmap table.
Acrobat Reader seems to use post table in this case.

Use identity cmap if it is missing from the TT file. Use unknown language
ID to activate in post table processing.

To avoid false positives run validation of post table to the files produced
by the same software as the reported sample file.

The path is committed as a rev. 8556.
Regression testing shows no differences.
