Why I get an error code 139 if I run this code?

I would like to know why I can build this project, but as soon as RSU receives the message I get an error 139. Even if I try to solve by removing the code inserted in onData function and run the project again, still doesn't work.

TraCIDemoRSU11p.h

TraCIScenarioManager* manager;
TraCICommandInterface* traci;

TraCIDemoRSU11p.cc

void TraCIDemoRSU11p::initialize(int stage) 
{
    BaseWaveApplLayer::initialize(stage);
    if (stage == 0) {
        manager = TraCIScenarioManagerAccess().get();
        traci = manager->getCommandInterface();
        traci->trafficlight("0").setProgram("tram_is_not_passing");
    }
}


void TraCIDemoRSU11p::onData(WaveShortMessage* wsm) 
{
    traci->trafficlight("0").setProgram("tram_is_passing");
}

veins version is 4.4 and omnet++ version is 5. I think the problem might be how I got traci interface in the initialize function, can anyone please explain how two modules use traci interface at the same time?

Edit:

As requested I am adding more information to the question.

Cross.net.xml

....
<tlLogic id="0" type="static" programID="1" offset="0">
    <phase duration="500" state="rGrG"/>
</tlLogic>
....

Cross.tls.xml

<tls>  
    <tlLogic id="0" type="static" programID="tram_is_passing" offset="0">
        <phase duration="4" state="ryry"/>
        <phase duration="20" state="GrGr"/>
    </tlLogic>

    <tlLogic id="0" type="static" programID="tram_is_not_passing" offset="0">
        <phase duration="999" state="rGrG"/>
    </tlLogic>
</tls>

As far as I know, OMNeT++ starts at 128 with its error codes and than adds the normal system error codes. This means that 139 = 128 + 11 and 11 is the error code for a segmentation fault.

Hence, it seems you are trying to use memory space which is not allocated or you are not allowed to use. You should run you simulation with Valgrind using ./memcheck to find out whether you have memory leaks.

EDIT: After Veins 4.7.1 a new run script was introduced. Now you can run your simulation with Valgrind using ./run -t memcheck.
