[Bug fortran/17077] New: adjustable size arrays crash

["scottb at uci dot edu" <gcc-bugzilla@gcc.gnu.org>]

Using adjustable size arrays in subroutines causes some memory alloc problem. 
It crashes my system, other times results in gibberish output.  

I have put a program below that fails.  It works on other f90 compilers.

WORKAROUND: When I replace adjustable size arrays (e.g. x(n,n)) with assumed
size arrays (e.g., x(:,:)) it all works fine. No idea why.

I use Mac OS X 10.3 (Darwin6.8) on dual G5. 
GCC version 3.5-tree-ssa-lno 20040811 (merged 20040718).
Configured with /gcc/configure --enable-threads=posix --enable-languages=c,f95


!Program that fails.
program p
implicit none
integer:: n
   n=3
   call foo(n)
   
contains
  subroutine foo(m)
    integer:: m,i
    real, dimension(m,m):: z
      ! Print z. It's OK here (all zero).
      do i=1,m
	write(*,*) z(i,:)
      enddo
      call foo1(z)
  end subroutine foo

  subroutine foo1(x)
    integer:: n,i,j
    real, dimension(:,:):: x
      ! Print z. It's not OK here (memory garbage).
      do i=1,n
	write(*,*) x(i,1:n)
      enddo
  end subroutine foo1
    
end program p
