Thread1: EXC_BAD_ACCESS (code=1,address=0x68)

Question

I am having this problem in ide Xcode. On line 8 the warning appears

Thread1: EXC_BAD_ACCESS (code=1,address=0x68)

The file . txt is in the same folder as the main.

void construir1(struct elemento **P_inicio){
    FILE *arq;
    struct elemento *p1;
    char c;

    arq=fopen("t1.txt", "r");
    *P_inicio = NULL;
    while ((c= getc(arq))!=EOF) {
        if (c!='\n') {
            p1 = malloc(sizeof(struct elemento));
            p1->x = c;
            p1->prox = *P_inicio;
            *P_inicio= p1;
        }
    }
    fclose(arq);
    return;
};

It really was something from the Xcode, it wasn’t pulling the txt. To resolve I went to "Product > Scheme > Edit Scheme > Run > Working Directory" and Linkei the folder where the code and txt is. By doing this the program ran normally on Mac.
