Description Marcos H. Woehrmann 2009-02-12 07:50:12 UTC 
A user reports that the attached file produces an "Error: limitcheck; OffendingCommand: addglyph" when 
read by gs8.63.  I've duplicated the problem with 8.63 and head (r9471).

The command line I'm using for testing:

  bin/gs -sDEVICE=tiff24nc -o test.tif ./Sample_HP5000PS.ps

Both Adobe Distiller 9.0 and Apple Preview read the file without error.

patch

The buffer for the compressed /CharString in Type 32 font was allocated for
the worst case of CCITTFaxEncode filter, which is 5x expansion.

The worst case in the sample file exceeded the max string size. The patch
limits
the string size to 65535, the maximum string length. The worst case is highly
unlikely to occur in the wild.
Comment 3 Alex Cherepanov 2009-02-12 13:08:48 UTC 
The patch is committed as a rev. 9472.

Regression testing shows no differences.
