Segmentation fault (core dumped)

[Geo572]

Hello @rquey
I have face problem like segmentation fault (core dumped) if I put the value of mean 0.95 and 0.055 even my Neper current version is 4.6.0.
l am waiting for your kind suggestions.

Thank you.

neper -T -n 400 -morpho "diameq:lognormal(2,0.05),1-sphericity:lognormal(0.95,0.03)" -domain "square(22.5,45)" -dim 2 -format geo

In the first example, the sphericity is very low, which is probably not what you want. The second example runs fine with version 4.6.1:

$ neper -T -n 400 -morpho "diameq:lognormal(2,0.05),1-sphericity:lognormal(0.055,0.03)" -domain "square(22.5,45)" -dim 2 -format geo
