Seems that on latest Debian builds (wheezy) that bug doesn't appear anymore, without LW6 code having been modified. Dunno wether bug came from dynamic loading libraries on amd64 or SDL specifically, but anyway, it's fixed.

For some reason, this segfault problem disappeared. The only major change was that now lib is dlopened/dlclosed several times since one needs to load it to know it's pretty printed "label" name. Sounds weird anyway, there's maybe a pointer error elsewhere. Heavy valgrind debugging might be required. Not a top-level priority, so this is postponed.

This problem only happens on x86_64 GNU/Linux platform.

When dlclosing SDL, the game crashes, error is located in libselinux.

Need to post details about this, I suspect the problem does come from selinux and not from LW6. A short 30-liner sample program that crashes would probably be required to fix this;

To be continued....
