Re: [xslt] How accurate is valgrind when ran against libxml2 ver 2.7.6 ?

Thanks. 

When you say it works "clean" there .. that is against 2.7.6?


Our API interface using AXIS2C is not aware of any dependencies 
on which  xml is used.

  Well, valgrind works cleanly with libxml2 here, there is
even a "make valgrind" Makefile target for nearly forever, and
running this is part of any libxml2 release.
  Now if you get lot of lost memory, it's probably due to the
fact you are not freeing some memory that libxml2 is passing to
you. Looking at the valgrind report should help you find where
that memory was allocated and where you received it.
