pango memory leak

[nerdy <nerds_ebook1 yahoo com>]

hello all,

futher to my previous mail about a memory leak that i suspect in the 
pango_font_description_set_family and pango_font_description_set_size functions, i observe that the leak exists in the latest version of pango. i am using fedora core 4     with pango version 1.8.1.

in my program i am continually increasing the size the font and this continually allocates memory. i would like to know the memory allocated for previous font size is not released/reused before allocating new memory for new font size. i also dont understand why new memory is allocated for every time the function ango_font_description_set_size is called. as far as i can see we will be resetting the font size for subsequent size requests.

please refer the program below.
