Segmentation fault: Cohesive Interface + Order 2 #281

Hi Romain,

I get a segmentation fault when I try to mesh a tessellation with cohesive interfaces and a mesh order of 2:

========================`    N   e   p   e   r    =======================

Segmentation fault (core dumped)

The tessellation was created with the following input: 

neper  -T -n 100 -domain 'sphere(10e-3,100):split(x):split(y):split(z)' -morpho 'graingrowth' -ori 'random' -oridescriptor 'rotmat' -format 'tess,ori'

Without the cohesive interface, meshing runs smoothly.

I hope you can help here and thank you in advance!

Best Mathias

I encountered the same problem while using neper.
