        c = strlen(buf);
        sprintf(format, "[%c%dll%c]  ", '%', c,
                pc->output_radix == 10 ? 'u' : 'x');

Looks like it should be 11, no?  You have 6 characters + '\0' + the %d,
which can be up to 1500 (BUFSIZE).  Of course, it wouldn't kill us to
use snprintf, either.

Cheers,
Jeff
