gfortran in 64-bit mode

gfortran in 64-bit mode

[Roger Ghanem]

I am having difficulties writing double precision variables using gfortran in 64-bit mode:
source code is

      double precision d
      d=0.
      write(0,*) d
      end

$ /usr/local/usr/bin/gfortran-4.0 -m64 -o pmain2 pmain2.f -L/usr/local/usr/lib
$ ./pmain2 
Illegal instruction


If I define d to be integer, then I am able to print it with no problem.

Configuration for this gfortran:

$ /usr/local/usr/bin/gfortran-4.0 -v
Using built-in specs.
Target: powerpc-apple-darwin8
Configured with: /Build/apple/gcc/build/obj/src/configure --disable-checking -enable-werror --prefix=/usr --mandir=/share/

apple-darwin8 --host=powerpc-apple-

Thread model: posix
gcc version 4.0.1 (Apple Computer, Inc. build 5224)

Thank you for your help
