------------------------------------

    Resolution: Cannot Reproduce

I've just run the 3 tests you mentioned against the latest revision of {{master}}.  No leaks in any of them.

Since this ticket was open I've submitted a bunch of fixes to allow REF_DEBUG testing of PJSIP - ASTERISK-27306.  Mostly this fixed failures to properly shutdown but a couple of actual leaks were addressed by that issue as well.  It's possible the leak you experienced was fixed by that.
