Question #668274 on Yade changed:
https://answers.launchpad.net/yade/+question/668274

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Azim,

the important part of the output is:

Backtrace:
/home/honzik/lib/x86_64-linux-gnu/yade-2017.01a/libyade.so(_ZN4Shop13growParticlesEdbb+0x188)[0x7ff0c3fb7368]
/home/honzik/lib/x86_64-linux-gnu/yade-2017.01a/libyade.so(_ZN24TriaxialStressController6actionEv+0x60e)[0x7ff0c41626be]

meaning that the problem is really TriaxialStressController, calling
growParticles [1] where the existence of Body is not tested in the for
loops. Please report a bug if you want to have it corrected.

cheers
Jan
