Segmentation fault problem

[Greatrebel]

Hi all,

I wrote a SystemC program which was compiled fine with g++, but as run, I got a segmentation fault:
Program received signal SIGSEGV, Segmentation fault.
0x0804a720 in mpsoc (n_slave=2) at ./src/main.cpp:149
149 router_mapfile << slave_array[i]->name() << endl;

The fault is located on this line router_mapfile << slave_array[i]->name() << endl; I attached the part of my code following, could anyone please help me figure it out. Thanks in anticipation.


vector<slave_cpu*> slave_array(n_slave);

for (i = 0; i < n_slave; i++)
{
slave_cpu slave(sc_module_name(sc_gen_unique_name("slave_cpu ")), SLAVE_REG);
slave_array.push_back(&slave);
}

/*generate the router port mapping file according the argument n_slave*/
ofstream router_mapfile("master.iport.map");

if ( ! router_mapfile ) { /*open failed*/
cerr << "cannot open master.iport.map for writing router port mapping" << endl;
exit(-1);
}
else {
cout << "generating the router port mapping file master.iport.map" << endl;
}
for (i = 0; i < n_slave; i++)
{
router_mapfile << slave_array[i]->name() << endl;
}

try replacing

vector<slave_cpu*>    slave_array(n_slave);
 

with

vector<slave_cpu*>    slave_array;
 

also I think your loop

for (i = 0; i < n_slave; i++)
    { 
    slave_cpu slave(sc_module_name(sc_gen_unique_name("slave_cpu")), SLAVE_REG);
     slave_array.push_back(&slave);
    }
 

should be

for (i = 0; i < n_slave; i++)
    { 
    slave_cpu * slave = new slave_cpu(sc_module_name(sc_gen_unique_name("slave_cpu")), SLAVE_REG);
     slave_array.push_back(slave);
    }
