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
