[xml] memory leak?

[Luca Padovani <lpadovan cs unibo it>]

Hi,

I have noticed that the size of a program repeatedly loading and freeing
XML documents constantly increases. I attach a test program to be run
with one argument, a XML document. The program then loops, so you can
trace its size with `top'.
Is anyone else experiencing the same behaviour? Or am I missing some
structure to be freed?
(I use 2.3.8).

Regards,
