Richard Mudgett has uploaded a new change for review. ( https://gerrit.asterisk.org/4444 )
Change subject: res_pjsip_outbound_authenticator_digest.c: Fix memory pool leak.
......................................................................
res_pjsip_outbound_authenticator_digest.c: Fix memory pool leak.
Responding to authentication challenges leaks PJSIP memory pools.
The leak was introduced with a pjproject 2.5.5 API change.
https://trac.pjsip.org/repos/ticket/1929 changed the API usage of
pjsip_auth_clt_init() to require the new API pjsip_auth_clt_deinit() to
clean up cached authentication allocations that get allocated with
pjsip_auth_clt_reinit_req().
ASTERISK-26516 #close
