¿Cómo puede estar fuera de límites el índice cuando en realidad está dentro de los límites como lo muestra el seguimiento de pila? Aunque el contexto puede no importar, estamos trabajando en un analizador / VM Lua para un IDE en la plataforma Netbeans y esto sigue aumentando. ¿Cómo puede ser esto? ¿Algún problema extraño de concurrencia? Gracias de antemano por cualquier idea.
