Memory leaks problem in gnustep 0.8.5

Memory leaks problem in gnustep 0.8.5

After numerous tests I have found out a problem with memory leaks in
gnustep - 0.8.5. (tested on Linux red hat 7.2, Solaris 8 ix86)
In the example I am enclosing, the application generates one window with
NSTextField item, and cyclically (by timer) redraws it.
After a few minutes it can be noticed that the application starts to
increase its memory, and after a few hours the size of memory will be
multiplied.
Thank you in advance for any help you can give me.
