The struct "Ffi_ArrowArray" implements "#derive(Clone)" that is inconsistent with its custom implementation of "Drop", resulting in a double free when cloned. Cloning this struct in "safe" results in a segmentation fault, which is unsound. This derive was removed from this struct. All users are advised to either: * bump the patch version of this crate (for versions "v0.7,v0.8,v0.9"), or * migrate to a more recent version of the crate (when using "<0.7"). Doing so elimitates this vulnerability (code no longer compiles).
