I am using valgrind on a g77 program and am getting
some peculiar results:

Cccccccccccccccccccccccccccccccccccccccccc
      program memty
      integer i
      i=360
      call fsub(i)
      end
C
      subroutine fsub(i)
      integer i
      double complex x(i,i)
      x(i,i)=complex(0D0,0D0)
      end
Ccccccccccccccccccccccccccccccccccccccccc

Valgrind gives an error of the form:

I do not know anything about valgrind, but the Fortran code is perfectly 
OK.  It uses an automatic array x in subroutine fsub that is dimensioned 
using the dummy argument i, which is an extension of Fortran 77, but 
allowed in Fortran 90 and supported by g77.

I tried your code using g77-3.3.4 as supplied by Debian on their testing 
platform (up-to-date as of Sunday 1/8/2004) and it performs perfectly.

I'm afraid someone else has to help you here (that's why I changed the 
subject).

Cheers,
