------- 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.
