Error code -11

[Nav]

Hi,

The following is the script I am using to test a new protocol. I have
placed a small part of this code under markers (///). The code
compiles and starts to execute. But If i set the value of
echoClient.SetAttribute ("MaxPackets", UintegerValue (9)); or any
values above 9, i get an error message Command ['/home/Navin/Documents/
ns-3.3/build/debug/scratch/wifi-olsr'] exited with code -11 . For
Values below 9 the scripts sucessfully executes.

Does anyone know what this error is? Can someone help me with this? I
have pasted my script and full ouput below.

Thank you.

[Mathieu Lacage]

I filed a bug to keep track of this issue:
http://www.nsnam.org/bugzilla/show_bug.cgi?id=547

feel free to add more comments there.

[Mathieu Lacage]

I tried to reproduce the problem but I can't. If you want to get more
help, you will have to provide a testcase we can run to reproduce the
problem.

Thanx a lot, Mathieu. After you posted the bug report at bugzilla, I
decided to do more rigourous testing on my code. After about 5 to 6
hours of debugging, I realised that the error was due to a function
that I had written for erasing all tuples of a new vector set that i
had created. After correcting the error, I stil haven't been able to
find out why it worked for some cases, but caused an error in others.
Now that I have fixed the code, everything seems to be working fine.
My sincere apologies for all the trouble I caused you.

Here is the piece of code that was causing the problems:

//error
void
RoutingTable::EraseAllTrafficLogTuple ()
{
for (TrafficLogSet::iterator it = m_trafficLog.begin ();
it != m_trafficLog.end (); it++)
{
m_trafficLog.erase (it);

}
}

This is the correction I made, that made the code work properly:

//correct
void
RoutingTable::EraseAllTrafficLogTuple ()
{
bool notOver=true;

while(notOver)
{
notOver=false;
for (TrafficLogSet::iterator it = m_trafficLog.begin ();
it != m_trafficLog.end (); it++)
{
m_trafficLog.erase (it);
notOver=true;
break;
}
}

}


Sorry for the trouble once again.

Thanking you,
Navin.
