--- 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
