Help with deleting array of pointers

Hi All,

I've got a class that declares an array of pointers like this:

Code:

class RemoraServer : public CommonApplication
{

................

      //these are the hosts this server maintains data for 
      RemoraHost  *host[MAX_HOSTS_PER_SERVER];
      int         numberOfHosts; //ongoing count of how many hosts we're dealing with right now

}; // end class RemoraServer

later in the code, it sets an index of that array to point to an object, thereby instantiating the object, like this:

Code:

            host[numberOfHosts] = new RemoraHost(hostName, hostRef, configFile);

            //we just gained a new host!
            numberOfHosts++;

I'm convinced the instantiation works, since I can interact with the newly created objects.

Now I want to delete all the objects and rebuild them, so I was trying this, but it doesn't work:

Code:

   
   //first destroy all of our current hosts, so we can re-initialize them all
   for (int i = 0; i < numberOfHosts; i++)
   {
      delete host[i];
   } //end for

All of my classes use virtual destructors.
My program SIGSEGV when it tries to delete the host[i], however (according to gdb) it stays within RemoraServer, so I don't think it's a problem with my RemoraHost code.

What am I doing wrong? (more than 1 answer is allowed. ). Thanks for any pointers (pun intended).

>My program SIGSEGV when it tries to delete the host[i]
The value of i at the time? Also the value of numberOfHosts and MAX_HOSTS_PER_SERVER would be useful. Also, can you come up with something we can compile and play with that still exhibits the problem? That way you'll get more than just guesses.

Just one guess for now. Did you remember to set numberOfHosts back to zero after you delete all the objects?

'i' is 0 when the SIGSEGV occurs.
MAX_HOSTS_PER_SERVER is 50
numberOfHosts == 1 at that point. There is 1 host, so that number is correct.
The code is too much to post, since RemoraHost has an array of pointers of other objects, which have arrays of pointers of other objects, etc...

I set numberOfHosts back to zero when I'm done deleting them, but it never finishes. The very first
delete host[0];
causes the SIGSEGV.

Oops, my bad. I was doing
delete [] host;
in the actual executable. I had changed it to
delete host[i];
and remade it but never loaded the new executable, so I was executing old code when I thouht I was executing new code. So far, testing the actual code I posted (duh), seems to work fine.

Thanks for your help.
