PDF File font problem
Using pdftotext on the attached "FRA_2803_DE_FD_1B686455.pdf" to extract the
text, the program is consuming memory indefinitely until exhausting all OS. The
tests were conducted in OpenSuse 12.1, Ubuntu 12.04 and Ubuntu 12.10, with
versions 0.18.0, 0.20.4 and 0.22.2 of pdftotext. Also tested with other tools
like pdftoppm pdftohtml and give the same result. The standard output of the
command is also attached (output.txt), showing that the font is not recognized.
I think there is a problem with rendering embedded fonts that are corrupt
within the PDF document. Try Open it with Adobe Reader and returns the
following message: "The font 'FrutigerLT-Cn' Contain a bad / BBox", but can be
saved as text
Due to the high memory consumption, try searching for memory leaks but running
valgrind on version 0.22.0 of pdftotext not report any leaks.</pre>
