Re: [xml] correct version of libxml2



Just out of curiousity - it _should_ be ok to call this within a library on a statically linked copy of 
libxml2, right?

Can you shed a little more light on why this call isn't always needed? In what situations is it necessary 
to call it?

 This frees up a few global variables allocated by libxml2. A few
kilobytes at most, but if they get deallocated while somehow the library
is still in use, the application is very likely to crash.
 So never call this in a library.
 In an app the only safe place to call it is close to the exit
It's still useful to make sure there is no memory leak when running a
program under valgrind or equivalent memory checker.
