Segmentation fault while processing the field

[Yue_Ma]

Hi,
I'm trying to run MPAS on my PC with Ubuntu 16.04, GNU 5,4.0, NetCDF 4.4.1.1, PNetCDF 1.8.1, PIO2. While I run the example 'supercell' and use

./init_atmosphere_model

processing the field, it shows

Segmentation fault(core dumped)

debug by gdb, shows

Any help on this would be greatly appreciated!

I was able to reproduce this locally, and the issue looks like it could be the allocation of what could be large variables on the stack in the box_rearrange_create routine. Does it help if you remove all stack size limits? For example, in tcsh you could try

limit stacksize unlimited

or in bash you could try

ulimit -s unlimited

.
