[MITgcm-support] seg fault

[Klymak Jody]

Hi All,

I'm getting the following during the first time step after I reduced  
my models resolution.  Looks like a segmentation fault:

I'd think I did something goofy in my data files, but if I run with  
debug level 2 the model runs fine.

If I run with my old resolution the model runs fine.

I checked my stack and it is unlimitted.

Any ideas what the issue could be?

Thanks Jody
