I'm running CAM5 on yellowstone, built from CESM1.0.5, using F compset with f09_f09 resolution.I start CLM with arbitrary initial conditions, setting:  CLM_FORCE_COLDSTART -val onThe model runs fine when I specify the default surfdata file, but if I run with modified surfdata, an error occurs immediately after opening the first history file:    1: Opened file test.cam2.h1.0000-01-01-00000.nc to write     1572864    ERROR: 0031-250  task 1: Segmentation fault Any idea what would cause this?  There are no other error messages and I'm at a loss.  Thanks.

I think this means that the model tries to write NaNs to the history file and hence crashes. Clearly this is due to a change that you made to the surface data.
