+ data-pointer overridden by set_gdbarch_data() or when the
+ architecture object is being deleted.
When a previously created architecture is re-selected, the
per-architecture data-pointer for that previous architecture is
- restored. INIT() is not called.

- During initialization, multiple assignments of the data-pointer are

- pointers are also deleted using FREE().
