[MITgcm-support] Segmentation fault

[Jill N Schwarz]

Hi Folks,

Sorry if this is an old one, but i did search the website and didn't 
find any help there.  (searched for MITgcm-support segmentation - any 
better alternatives, let me know!)

I get an immediate Segmentation Fault when i start running my new 
configuration.  This isn't a platform problem, as another configuration 
runs just fine..  which means i've done something daft as usual..  i've 
double checked size.h and the other input files i've altered but can't 
see anything obvious, so my question is simply;  does anyone have any 
tips as to where this might arise?

Brief info;  the grid is 359 x 76 cells, with DELX and DELY supplied - 
their dimensions definitely agree with the bathymetry dimensions.  exf 
forcing is on with allow_exf_interpolation (from 2deg gridded files) and 
useExfYearlyFields = .TRUE.,  using a normal year 6 hourly forcing.  But 
since the Seg fault happens instantaneously, i guess the reading-in of 
these files doesn't even begin.  The things i've changed are the forcing 
files, the grid size and switched off OBCS.  I'm running on a linux 
cluster with 17GB ram, so i can't see size being a problem.

Muy gracias for any assistance!
jill.
