the getArgumentCount() call in IfcEntityInstanceData destructor isn't virtually dispatched so it returns 0 instead of correct number of arguments => memory leak added IfcEntityInstanceData::clearArguments() which clears all arguments and resets the attributes_ field to nullptr Remove unnecessary copy in IfcEntityInstanceData::setArgument() when argument is created at the call site (no more leak of original argument) Fix memory leak in IfcFile: delete entities from both byid and entity_file_map
