  If you print this->name or this->entry->module->name, you'll see which
module it is.

  Odds are it's the same kind of nonsense as rlm_eap_tls.  The parsed
configuration items are buried inside of a second structure, rather than
being in the main instance data.

  That fix should be easier.  Add a "detach" method to the module.  Call
cf_section_parse_free() on the real pointer.  And then free() the instance.
