* trans_array.c (gfc_trans_array_constructor): Temporarily
realign loop, if loop->from is not zero, before creating
the temporary array and provide an offset.
PR fortran/35959
* trans-decl.c (gfc_init_default_dt): Add gfc_ prefix to name
and allow for NULL body. Change all references from
init_default_dt to gfc_init_default_dt.
* trans.h : Add prototype for gfc_init_default_dt.
* trans-array.c (gfc_trans_deferred_vars): After nullification
call gfc_init_default_dt for derived types with allocatable
components.
