As Alex reported in bug 1853:

Actually. There is still segfault with NS_LOG=*, but it is probably completely different story (though I thought we have already fixed that...)

(first column is stack size.... it's huge)

example that failed was a trivial one (and I'm using the latest ns-3-dev):

#include "ns3/core-module.h"
using namespace ns3;

int
main (int argc, char *argv[])
{
  Simulator::Stop(Seconds(10));
  Simulator::Run ();
  Simulator::Destroy ();
}
