Array restriction in g77

[Olaf Cirpka]

I have installed the latest release of g77 on a pentium III running under
Debian Linux (kernel 2.0.38).

g77 version 2.95.2 19991024 (from FSF-g77 version 0.5.25 19991024)
i686-pc-linux-gnu

The computer has 1 GB RAM, and the system recognizes the memory
(/proc/meminfo contains "MemTotal:   1032628 kB"). However, when
I define arrays that use more than 512 MB RAM, I receive the error message
"array too large to handle".

Example: test.f

      PROGRAM HALLO
      DOUBLE PRECISION A(67108864)
      WRITE(*,*) "HALLO"
      END

End example

output for g77 test.f:

         DOUBLE PRECISION A(67108864)
                          ^
Array `a' at (^) is too large to handle

End output

With A(67108863) everything is fine.
