gfortran seems to deallocate a pointer which was not allocated or need not be
allocated. The program below compiles, but when executed returns the following
error message:
a.out(8814) malloc: *** error for object 0x1fa2: Non-aligned pointer being
freed
*** set a breakpoint in malloc_error_break to debug
Bus error
(Happens for Linux x86 and x86-64 as well as MAC OS X)
The code is:
program main
type :: string
character,dimension(:),allocatable :: chars
end type string
type :: string_container
type(string) :: string
end type string_container
type(string_container), pointer :: ptr
call set_ptr (ptr)
contains
subroutine set_ptr (ptr)
type(string_container), pointer, intent(out) :: ptr
ptr => null ()
end subroutine set_ptr
end program main

------- Comment #2 from burnus at gcc dot gnu dot org 2009-07-25 06:55 -------
CONFIRM. Affects all GCC with pointer intent (4.3/4.4/4.5). For
subroutine set_ptr (ptr)
type(string_container), pointer, intent(out) :: ptr
one shall not deallocate the pointer. The pointer intent is different from a
non-pointer intent:
set_ptr (struct string_container * & ptr)
{
if (ptr != 0)
{
if (ptr->string.chars.data != 0B)
{
__builtin_free (ptr->string.chars.data);

Thanks for the report. FIXED on the trunk (4.5); I will soon backport it to
4.4/4.3.
(Workaround: Do not use INTENT for pointers [which is a Fortran 2003 feature].)

I forgot to do a "svn add" - and I forgot to do a "svn status" to find such
problems. It is not corrected.
