CohesiveTriaxialTest preprocessor segfaults

[Jérôme Duriez]

Hi,

I get "core dumped" crashes using CohesiveTriaxialTest preprocessor (FileGenerator) with:

#### Crashing script ####
simu = CohesiveTriaxialTest(numberOfGrains=4)
simu.generate('simu.yade')
O.load('simu.yade')
O.step()
################
(or just using the "Generate" part of the GUI)

### Affected YADE versions ###
On my computer, it affects
- yadedaily (Yade 2018.02b-74-c261ac3~xenial)
- the current trunk version (Yade 2018-04-12.git-c261ac3)

I'm attaching the whole output when running a debug trunk version.
