Is log4cxx mature ?

Hi,
  Sorry about the subject but that in fact is my question. Is it
recommended to use log4cxx in c++ app for windows? I mean a basic test
revealed a memory leak of 4 bytes every time you log (stack trace from
purify is attached below and I am using static library built with
runtime library multithreaded debug dll on vc++.net 2003 to build
log4cxx). 
   I would be happy if someone can tell me if this is a known problem on
windows. I tried following up threads on mailing list but all of them
ended up no where. I need this working ASAP. So any kind of help would
be appreciated.

Will I have to wait for the next version so as to be able to fix the
above mentioned things?

Please keep my email: Lazybug@xxxxxxxxxxxx in cc while replying


Thanks and Regards,
