Out of bounds error. SystemC simulation with Modelsim

Hi

When I simulate my SystemC project in Modelsim I get this error:

Error: (vsim-6596) Out of bounds:
# In process: sc_main/hermes_2d/thread_p_2 @ 872800 ns
# ** Fatal: Fatal SystemC error detected, exiting...

From what I could ascertain according to the results collected, the logic is correct.

Heres is the code:

for(int i = 0; i < 16; ++i)
{
          sc_spawn(sc_bind(&hermes_with_pkt_codec_vhd_bfm::sender, this, i));
		  sc_spawn(sc_bind(&hermes_with_pkt_codec_vhd_bfm::receiver, this, i));
}





void receiver(unsigned int agent)
 {
		 wait(reset);  sc_core::sc_lv<16> tx_re_s;
         sctg::BufferInterface* buffer = _confIf->getBufferIf(agent);
		 tgPacket* packet = 0;

  if(!buffer)
  {return;}  
  while(true)
  {
	  
            sc_core::wait(clk_ip->posedge_event());
			packet = new tgPacket;
		
			do { sc_core::wait(clk_ip->posedge_event()); }
            while(tx_av.read()[agent] == sc_dt::SC_LOGIC_0);  
   
            packet->address = tx_data.read().range((agent+1)*32-1, agent*32).to_ulong();
		  
			do { sc_core::wait(clk_ip->posedge_event()); }
           while(tx_av.read()[agent] == sc_dt::SC_LOGIC_1);		  
		  
            unsigned int tam	=  tx_data.read().range((agent+1)*32-1, agent*32).to_uint();
		  
			
		  
			for(unsigned int i = 0; i < tam; i++)
			{  
				   do { sc_core::wait(clk_ip->posedge_event()); }
                   while(tx_free.read()[agent] == sc_dt::SC_LOGIC_0);  

					
	
				   packet->data = new unsigned char[sizeof(unsigned int)];
                   unsigned int data = tx_data.read().range((agent+1)*32-1, agent*32).to_uint();
                    *reinterpret_cast<unsigned int*>(packet->data) = data;
           
                  packet->size += 32/8;
		  
				   do { sc_core::wait(clk_ip->posedge_event()); }
                  while(tx_free.read()[agent] == sc_dt::SC_LOGIC_1);
  
           }
		  
            // Wait until packet fits to agent's buffer
            while(buffer->rxSpaceLeft() < packet->size)
            {
                    wait(*(buffer->rxGetReadEvent()));
             }
  
           buffer->rxPutPacket(packet);
           packet = 0;
           sc_core::wait(clk_ip->posedge_event());
      }
}

Thanks
