Doesn't look like it should segfault right?

int readf()
{
    char ch[3];
    ch[1] = '\0';
    FILE *input = fopen(infile, "r");
    while ((ch[0] = getc(input)) != '\n' && ch[0] != '\\' && ch[0] != EOF)
    {
        strcat(lbuf, ch);
        printf("char: %s\n", ch);
    }
    printf("%s", lbuf);
    return 0;
}
