The r14-6076 change changed the allocation of attribute tables from
table = new attribute_spec[2];
to
table = new attribute_spec { ... };
with
ignored_attributes_table.safe_push (table);
later in both cases, but didn't change the corresponding delete in
free_attr_data, which means valgrind is unhappy about that:
