[ndnSIM] Not able to visualise the simulated code

[sai gautams]

Hi Yogr,
I'm facing the following issue when I try to debug my code in ndnSIM. I
don't understand how to deal with this fault. Can you please help me out?
Thank you.

Program received signal SIGSEGV, Segmentation fault. 0x00007ffff7f584d1 in
ns3::SimpleRefCount<ns3::Object, ns3::ObjectBase, ns3::ObjectDeleter>::Ref
(this=0x6465697272616320) at ./ns3/simple-ref-count.h:107 107    NS_ASSERT
(m_count < std::numeric_limits<uint32_t>::max())
