I have stared at this problem for a while now, but I'm still puzzled about its
origin. All I could come up with is this ad-hoc patch:

Index: gcc/fortran/trans-expr.c
===================================================================
--- gcc/fortran/trans-expr.c    (revision 168301)
+++ gcc/fortran/trans-expr.c    (working copy)

   rhs = gfc_copy_expr (code->expr1);
   gfc_add_vptr_component (rhs);
+  gfc_get_derived_type (rhs->ts.u.derived);
   gfc_add_def_init_component (rhs);

   sz = gfc_copy_expr (code->expr1);


This does not solve the problem fully, but it reduces it to PR46448:
