Problem on save superquadric state

Hello !

I've been using LIGGGHTS for around a year now mainly with spherical particles. I want to create a '2D' model using cylindrical particles, it would be a 3D plan symmetrical model. To do so I created superquadric particles with N1=8 and N2=2. But whenever I try to use the command 'write_data' to save state the program crashes. I get the following error :

write_data data.*
System init for write_data ...
double free or corruption (!prev)

SIGINT/SIGTERM caught - Writing restart on next occasion and quitting after that.

Does anyone knows how to fix it?

Thanks in advance,
