The following code crashes with segmentation fault on `deallocate(copy)`:
module mytype_mod implicit none type :: mytype integer :: val contains final :: finalize_mytype end type contains subroutine finalize_mytype(this) type(mytype), intent(inout) :: this end subroutine end module program test_prg use mytype_mod implicit none call test() contains subroutine test() type(mytype), pointer :: main(:), copy(:) allocate(main(3)) allocate(copy, source = main) deallocate(copy) end subroutine end program
If I make the final procedure `elemental`, then it works. This also seems to have something to do with `source` and `pointer` attributes since I couldn't reproduce the crash without them. To the best of my knowledge, this code should be valid. Tested with ifort 22.214.171.124.
