[ncl-install] floating overflow with Periml

[Jemma Wu]

Hi all,

I have built and installed ncarg.v5.2.1 under OpenSUSE 11 with Intel
compilers. Now I have a problem with calling Periml (Gridal package) in my
fortran program. The program can be compiled and run (appears correctly) if
I don't add the float point exception flag (fpe0). However, if I add the
fpe0 flag and compile and run it, then it will stop with a floating
overflow. I debugged it and found it is with the Periml call.

I then found an example (tgrida) in ncarg with Periml and tested it with
adding the fpe0 option, and it also have the float overflow problem. My
compilation options are as follows.

ifort –fpe0 -traceback -O0 -o tgrida tgrida.f -L/usr/local/ncarg_build/lib
-lncarg -lncarg_gks -lncarg_c -lX11 -lXext,

and the running results are

~/model/ncl_ncarg-5.2.1> ./tgrida
forrtl: error (72): floating overflow

Does anyone know what's wrong?

Any comments would be appreciated.
