Comment:
Since the invalid free seems to occur in the OSG library in `osgDB::Registry::initDataFilePathList()`, [which seems to be](https://github.com/openscenegraph/OpenSceneGraph/blob/f4c4f76370f5b6f8c33cdc6e1e65443c369363e6/src/osgDB/Registry.cpp#L517) fetching the environment variable `OSG_FILE_PATH`.

@pullmoll replied to my initial email that `fgfs` was working fine for them. I'm wondering if they have exported this variable with something that doesn't cause the abort?
