Re: [Jepp-users] Simple test which shows memory leak in Jepp.

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi Jon,

I think we have a slightly modified version of Jepp in FABLE. I  
remember turning off OPTIMISATION at one point. We should do a diff on  
the Jepp source code in our repository and the one on the Jepp  
download sight to be sure.

Any changes to the source code might explain why we have a memory leak  
and Mike does not see one.
