Corrija este error cambiando 'return err' por 'goto free_regions'. Este error fue encontrado por un analizador estático. El análisis emplea verificación diferencial para identificar operaciones de seguridad inconsistentes (por ejemplo, comprobaciones o kfrees) entre dos rutas de código y confirma que las operaciones inconsistentes no se recuperan en la función actual o en las personas que llaman, por lo que constituyen errores. Tenga en cuenta que, como error encontrado mediante análisis estático, puede ser un falso positivo o difícil de activar. Varios investigadores han realizado una revisión cruzada del error.
