[MITgcm-support] compiler flags to make output human readable

[Jean-Michel Campin]

Hi Jonny,

I don't know if this will help, but you could check (where you compile)
the end of "genmake.log" if you have the flush system command
available (HAVE_FLUSH='t'). If you have it, then adding 
 debugMode=.TRUE., 
in eedata will force to flush STDOUT and STDERR unit after each write.
This way, you might get an idea of where this error comes from by
checking the end of all STDOUT.* 

Cheers,
Jean-Michel
