[Bug fortran/32795] [4.3 regression] allocatable components are nullified prematurely

[dfranke at gcc dot gnu dot org]

------- Comment #2 from dfranke at gcc dot gnu dot org  2007-07-18 17:12 -------
In the code below, X%I is set to 0B, although the data should be still
available:

$> cat pr32795.f90
  type :: a
    integer, allocatable :: i(:)
  end type a
  type(a) :: x, y

  x = a ((/ 1,2,3 /))
  y = a (x%i(:))         ! memory leak
  print *, "<", x%i, ">"
end

$> gfortran-svn -fdump-tree-original pr31320.f90 && ./a.out
 <>

The dump shows:
    x.i.data = 0B;
before the print statement. An attempt to dealloc x afterwards follows (thus
the leak).

I will see whether I can do anything. If anyone beats me to, be welcome.
