It is the pointer assignment in subroutine init

self%x => a

that fails.

Created attachment 54856
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54856=edit
fixed testcase class_dealloc.f90

As I just see, the first attachment does not show the bug as return value "a"
of function create is declared as "class(t), dimension(:), pointer". And as
described in the initial report, with class instead of type, there is no error.

The fixed attachment declares "a" as "type(t), dimension(:), pointer". This
shows the described error. It is still present in the current 13 development
branch.
