Subject: [Bug fortran/48351] [OOP]  Realloc on assignment fails if parent component is CLASS

--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-03-30 08:04:13 UTC ---
trans-array.c's gfc_is_reallocatable_lhs fails at:

6859      /* All that can be left are allocatable components.  */
6860      if ((expr->symtree->n.sym->ts.type != BT_DERIVED
6861           && expr->symtree->n.sym->ts.type != BT_CLASS)
6862            || !expr->symtree->n.sym->ts.u.derived->attr.alloc_comp)
6863        return false;

The reason is that the CLASS wrapper does not set:

(gdb) p expr->symtree->n.sym->ts.u.derived->attr.alloc_comp
$3 = 0

Only the "_data" component has this value set for its type:

(gdb) p expr->symtree->n.sym->ts.u.derived->components->ts.u.derived->name
$12 = 0x2aaaaab42f98 "foo_t"
(gdb) p
expr->symtree->n.sym->ts.u.derived->components->ts.u.derived->attr.alloc_comp
$13 = 1
