RE: Memory leak report for Axis2c 1.4
svn log says: Wrappers for the new XML parser.
After looking at the code change, I am still scratching my head. Maybe
you can shed more light from this?
http://svn.apache.org/viewvc/webservices/axis2/trunk/c/axiom/src/parser/
guththila/guththila_xml_reader_wrapper.c?r1=525104&r2=549072&diff_format
=h
I appreciate your help.
Thanks

You could have a look at the rationale by looking at the svn log for
that change.
