Description Bruno Coudoin 2008-09-28 00:42:14 UTC

When GCompris uses libxml2 2.7.1 it loops indefinitly in the xmlStringDecodeEntities if we pass it an &gt;

This bug was first tracked on the OLPC project under:

This is a minimal test case showing evidence of the bug.

This code worksfine on older version of libxml2. Perhaps it's not a valid use but please tell me what I am doing wrong if it's not a libxml2 bug.

Comment 2 C. Scott Ananian 2008-09-28 14:32:28 UTC

Additional information: works in libxml2.i386 0:2.6.32-3.fc9/libxml2-python.i386 0:2.6.32-3.fc9; breaks in libxml2.i386 0:2.7.1-1.fc9 / libxml2-python.i386 0:2.7.1-1.fc9.

I can't reproduce with problem with the current version (2.7.3 - git)

  I assume it was a temporary problem
