[MITgcm-support] I/O issue with CTRL_SET_PREC_32

[Maëlle Nodet]

Patrick,

I rerun the unchanged verification/natl_box_adjoint (without control  
precision set to 32): works fine.
Then I turned the control precision to 32: same problem as before  
"attempt to access non-existent record..."

This was on dolphin (linux_amd64_ifort) and also on Tom's pc (pentium  
proc with g77).
I think the MITgcm version we use might be 3 weeks old.

Thanks for your help,
Cheers,
Maelle
