Subject RE: Memory leak report for Axis2c 1.4
Date Thu, 31 Jul 2008 22:17:29 GMT
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.
