Fix missing deep copy when assigning a DT constructor to an array
This adds the missing deep copy when assiging a constructor of a derived
type with allocatable components to an array.
The check for constantness is removed so that the deep_copy argument passed
to gfc_trans_scalar_assign is set to true.
PR fortran/67721
gcc/fortran/
* trans-expr.c (gfc_trans_assignment_1): Remove the non-constantness
condition guarding deep copy.
gcc/testsuite/
* gfortran.dg/alloc_comp_deep_copy_3.f03: New.
