Re: [Agar] valgrind output of agar app

Hi,

Thank you for your feedback,


Could you test this again with current SVN? A number of leaks following
AG_Destroy() have been addressed since version 1.3.4.

You don't need anything other than AG_Destroy() at the end of your program.

I've attached the valgrind suppression file I'm using on my Linux/amd64
workstation.
