Hello

I have to release the memory allocated on the native heap manually in T.U.E.R when going from a level to another one in order to manage this heap in a timely manner, i.e without relying on garbage collection.

However, calling CLinker.freeMemory() on a direct NIO buffer used to store texture data stops the program:
[java] AVERTISSEMENT: Attempting to update a texture that is not currently on the card.
     [java] double free or corruption (!prev)

BUILD FAILED
/home/gouessej/Documents/programmation/java/workspace/tuer/pre_beta/build.xml:430: Java returned: 134

Am I doing something completely stupid? By the way, I use OpenJDK 17. I'll try OpenJDK 19 as soon as possible.
