Segmentation fault during Connect Conforming inner and periodic sides

[rschoene]

When using the attached file with hopr, I get a segmentation fault during the step
Connect Conforming inner and periodic sides...

System:

• Intel Haswell
• BullX SCS4
• Linux 2.6.32-696.30.1.el6.x86_64
• intel 18.0.1 20171018
• Intel-MPI 18.0.1 20171018
• hopr commit 7ce0fe1

Build procedure:

FFLAGS="-I/sw/global/compilers/intel/2018/impi/2018.1.163/include64/ -O0 -g" cmake ..
make

GDB prints:

I attached the parameter_hopr_unstr_large.zip file, which I used via
