possible bug in g77

["L.L. Salcedo" <salcedo at ugr dot es>]

This is to report a possible bug found in g77.

The source file:

      dimension  a(250000,250000)
      a(1,1)= 0.
      write(*,*) ' a',a(1,1)
      end

The output:

$ /usr/bin/g77 source.f
$ ./a.out
  a
$

I think there is a bug because the output was 'a' instead of '  a  0.'
(When I use  'dimension  a(40000,40000)' the compiler gives instead
         dimension  a(40000,40000)
                    ^
Array `a' at (^) is too large to handle
)

I am using RedHat 7.2. In addition g77 -v  gave
