segmentation fault for 01_basics/GaN_infiles

[tsiayigong]

Dear developers,
When I try to run the basic examples for GaN via extract_forceconstants -rc2 100 --polar -s 50, I obtain some error:

 ... reading unitcell

If you have any suggestion?

Hi, I also have this problem. Have you solve it ?

I also have this problem.

OS: Ubuntu 22 LTS
extract_forceconstants version: 1.2
Compiler: Intel Fortran compiler mpiifort version 2021.11.1. I tried with both -O0 and -O3 optimization flags.

The error seems to be related to symmetry checking. Compiling with -g -traceback debuging flag gives the following error:
