cannot attach SCTP agent to multiface node

Hello!


In my scenario, I have two networks: WiMAX and WLAN. A multiface mobile
node will move between those two networks.

The multiface mobile will send a CBR traffic.

I want to attach the *SCTP *agent to the CBR traffic. But I got
"segmentation fault (core dumped) "


The following code represents the initiation of the sctp protocol, the cbr
traffic and what I did to establish the communication:


    Agent/MIHUser/IFMNGMT/MIPV6/Handover/Handover1 set debug_ 1
    set handover [new Agent/MIHUser/IFMNGMT/MIPV6/Handover/Handover1]



    set stcpvideo_ [new Agent/SCTP]

    $stcpvideo_ set fid_ 0
    set cbrvideo_ [new Application/Traffic/CBR]
    $cbrvideo_ set packetSize_ 1000 ;# 1500
    $cbrvideo_ set interval_ 0.1
    $cbrvideo_ attach-agent $stcpvideo_
    set nullvideo_ [new Agent/Null]

    set stcpvideo_2 [new Agent/SCTP]

    $stcpvideo_2 set fid_ 1

    set cbrvideo_2 [new Application/Traffic/CBR]
    $cbrvideo_2 set packetSize_ 1000 ;# 1500
    $cbrvideo_2 set interval_ 0.1
    $cbrvideo_2 attach-agent $stcpvideo_2
    set nullvideo_2 [new Agent/Null]

        $ns attach-agent $router0 $stcpvideo_
        $multiFaceNode_($j) attach-agent  $nullvideo_ $iface2_($j)
        $ns attach-agent $router0 $nullvideo_2
        $multiFaceNode_($j) attach-agent  $stcpvideo_2 $iface2_($j)
        $multiFaceNode_($j) connect-agent $stcpvideo_ $stcpvideo_2
$iface2_($j)
        $handover add-flow $stcpvideo_2 $nullvideo_2 $iface2_($j) 2
        $handover add-flow $nullvideo_ $stcpvideo_ $iface2_($j) 1

 Thank you!

Regards.
