- Pasting a material would free the materials local node-tree, leaving it in the depsgraph which would then tag the freed ID (from deg_graph_clear_id_recalc_flags). - texpaintslot, gp_style pointers were copied into the clipboard without being cleared or duplicated, allowing for freed memory access later on. - A shallow copy from the cliboard into the material could also cause these pointers to be overwritten and leak memory. Resolve by calling material_free_data before performing a shallow copy and adding material_clear_data which ensures these pointers aren't copied into the clipboard.
