Memory leaks in Kannel

Hi all,

I'm using the kannel version 1.4.0 and I wanted to
keep using this version, since I have made slight
changes.
I have noticed that there are some memory leaks in,
1.4.0 that I confirmed at http://www.kannel.org/news.shtml.
 - Fixed memory leaks for concat message handling.
 - Fixed memory leaks in smsbox.

I wanted to fix those problems on version 1.4.0, not
upgrading to 1.4.1. Anybody can provide me a patch to
fix this? or can give me any code, easy tips, etc. so
that I can fix the problem changing the code.


Regards,
Carlos Parada
