Description Stefan Behnel 2010-02-26 13:24:46 UTC 
Steps to reproduce:

1) Download and extract the following archive of docbook XML files:

http://diveintopython.org/download/diveintopython-xml-5.4.zip

2) Run

xmllint --noent diveintopython-5.4/xml/diveintopython.xml

A run under valgrind indicates that the parser is trying to access entity data from a memory location that was previously freed. I suspect that the data was freed because it originally came from an external entity.

The same issue goes for libxml 2.7.7.dfsg-2 and 2.7.8.dfsg-3
It faults on mapnik style files, better written here http://trac.mapnik.org/ticket/566

Steps:
svn checkout http://svn.openstreetmap.org/applications/rendering/mapnik
xmllint --noent mapnik/osm.xml

diveintopython.xml works for me with current git master under ASan, and with 2.9.4 under Valgrind. So I guess this was fixed.
