Hello All,

I'm trying manage a vector of 10528 bytes, I made a C++ routine and works
but, when I work with my routine in GNU Radio, It do really extrange things
and I don't know why. I try to explain:

My Routine in GNU is:

ex_scramb_ss::general_work (int noutput_items,
                               gr_vector_int &ninput_items,
                               gr_vector_const_void_star &input_items,
                               gr_vector_void_star &output_items)
        const unsigned char *mpeg2package = (const unsigned char *)
        unsigned char *mpeg2packageout = (unsigned char *) output_items[0];     
        unsigned char result
        printf ("hello");
        for (short i=0;i<10528;i++){

And my test in python is:

from gnuradio import gr, gr_unittest
import ex

class qa_ex (gr_unittest.TestCase):

    def setUp (self):
        self.tb = gr.top_block ()

    def tearDown (self):
        self.tb = None

    def test_001_escramb_ss (self):

    src_data=(0x47, 0xA7, 0x15, 0x38......(10528))
    src = gr.vector_source_b (src_data)         
    dst = gr.vector_sink_b ()   
    sqr = ex.suma_ss ()         
    self.tb.connect (src, (sqr,0))      
    self.tb.connect (sqr, dst)  
    self.tb.run ()
    result_data = dst.data ()           
if __name__ == '__main__':
    gr_unittest.main ()

Ok, I put printf("hello") and hello is printed 4 times and I don't know why,
only I connect one time my block, besides, when I print mpeg2package[i], my
entry, is printed 4 times and with diferents value (71 0 0 184), this isn't
sense because I don't modify, and I can't, my entry
