problem in memory -- strlen

[radicaled]

Hi, I've been working in a program for the school that use a recursive call to the function. The problem is that I have to use that function almost 86000 times, because I'm reading a dicctionary.
The problem occur in the ten or twelve call to the function and it appear in when I use a strlen to see the size o string.
That's why I think it's a problem with the memory.

I leave you the function to see if I'm doing something wrong.

Thanks

void Insertar(Arbol *lista, char *numero, int posicion) {
   pNodo nuevo, anterior;
   char letra[10];
   int trad;
 
   fflush(stdout);
 
   strncpy(letra, numero, 1);
   trad = atoi(letra);
   nuevo = (pNodo)malloc(sizeof(tipoNodo));
   nuevo->numero = trad;
 
   if (strlen(numero)== 1){
      InsertoInterna(&nuevo->listaInterna, posicion);
   }
 
   if (ListaVacia(*lista)){
      nuevo->siguiente = *lista;
      *lista = nuevo;
     if (strlen(numero)>1){
         if ((int)numero[0]>=(int)numero[1]){
            Insertar(&nuevo->izquierda, ++numero, posicion);
         }
         else{
            Insertar(&nuevo->derecha, ++numero, posicion);
         }
      }
   }else{
        anterior = *lista;     
        while ((anterior->siguiente) && (anterior->numero != trad))
              anterior = anterior->siguiente;
 
      if (anterior->numero == trad){
         if (strlen(numero)>1){
            if ((int)numero[0]>=(int)numero[1])
               Insertar(&anterior->izquierda, ++numero, posicion);
            else
               Insertar(&anterior->derecha, ++numero, posicion);
         }
         free(nuevo);
      }
      else{
         nuevo->siguiente = anterior->siguiente;
         anterior->siguiente = nuevo;
         if (strlen(numero)>1){
            if ((int)numero[0]>=(int)numero[1])

if (strlen(numero)>1){

strlan() will crash your code if the pointer is null. Are you sure numero is not null?

If it's not null then, it will count characters until it finds a \0 regardless of how much memory has to be searched. Are you certain that you are not overrunning an array boundary?

I assume you have using your debugger to step through the calls so yo can see the state of your variables as things progress. You are using your debugger, right?
