Description
When on-demand UdpFace is being closed, the object itself is still alive.
To check:
in
udp-face.cppon line 128 (just after close()):NFD_LOG_ERROR("Remaining references: " << this->shared_from_this().use_count() - 1);run NFD
from another machine either send UDP packet with
ncor establish udp face towards the machinewait
Expectation: Remaining references: 0 (or crash)
Actual: Remaining references: 2
This may not be just UdpFace, I just discovered it with idle UdpFace. Where could we forgotten this face?

This is legitimate bug and I found the reason. onFail event emitter is never cleaned, resulting in a self-referenced shared_ptr (face->onFail indirectly reference face).
This applies to all faces. Will submit a patch to fix the problem---will clean onFail inside Face::fail()
