eofudf fatal error

Most likely you did not choose the right "resz" parameter setting in
the eofudf source,
see the remark at the bottom of
http://www.atmos.ucla.edu/~munnich/grads/EOF/.
The correct setting depends on the compiler you are using.  For 32bit
OS it is either
1 or 4, so try  the other value.  If successful, let me know which
Fortran compiler
and resz you needed to  use.
