I've run into the same situation using the ifort compiler
with CAM3 and have not been able to resolve the problem (I
ended up switching back to the pgf90 compiler before digging
into it too far).

CAM3 introduced some new namelist parameters (fincl1lonlat,
fincl2lonlat, etc.) for specifying the lat/lon regions for
which model variables should be written to the history files.

The values for these fincl*lonlat namelist parameters are stored
in an array fincllonlat in the history module.  At around
line 1716 of that module, the code tests each string in fincllonlat
to see if it is empty:

do while (fincllonlat(ff,t) /= ' ')
   lonlatname(ff) = trim(fincllonlat(ff,t))
   call getlatind(lonlatname(ff),latind(ff,1),latind(ff,2),latname(ff))
   call getlonind(lonlatname(ff),lonind(ff,1),lonind(ff,2),lonname(ff))
...

For some reason ifort thinks these strings are not empty,
even if the input namelist left these fincl*lonlat parameters
undefined.  The result is that getlatind() and getlonind()
are called when they shouldn't have been.

What is odd is that the code contains other, similar tests on
namelist parameters fincl, fexcl, fhstpr and fwrtpr in the
fldlst() subroutine, and no problems occur if these are empty
strings.

I'm not sure if this problem might be dependent on the ifort version.
I think I've tried only with version 8.0 under Redhat and Slackware
linux.

Regards,

Norm
