ns-3-dce test.py crashes after build sucess

[Emilín Amy Hao Jingjing]

Hello ns-3 group,

My bake system works fine and successfully builds ns-3-dce, but it fails to run source/ns-3-dce/test.py, all four test cases crash, named segmentation fault which returns 139.

Anybody recognise this problem and can help me with it ?

Don't know how to configure dynamic library path for the platform 'linux'; assuming it's LD_LIBRARY_PATH.
Command ['/home/emilin/ns3-dce-workspace/bake/source/ns-3-dce/build/bin/dce-iperf'] terminated with signal SIGSEGV. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

Thanks,
