Segmentation fault on lsquic_engine_destroy

[sergePSE]

May I ask you for a hint in the next issue or maybe an advice, what can be additionally checked?
Segmentation fault: lsquic_full_conn.c:762
if (conn->fc_conn.cn_enc_session)
conn->fc_conn.cn_esf->esf_destroy(conn->fc_conn.cn_enc_session);

conn->fc_conn.cn_esf does not exist, while conn->fc_conn.cn_enc_session exists.
Error appears after https://github.com/sergePSE/thesis_share/blob/master/quic_probe/src/quic_engine_holder.c:110

conn->fc_conn.cn_esf does not exist, while conn->fc_conn.cn_enc_session exists

This likely means indicates that contents of memory pointed to by conn are invalid. This is because cn_esf is only assigned once, in the constructor. On the other hand, the call to destroy cn_enc_session is pretty far down in the destructor, so all preceding cleanup function calls were OK. Perhaps something fishy is done in the on_conn_closed callback?

I would try tracing the connection lifetime: -l conn=debug.

Thanks for response, debugging level was helpful and I've done a mistake in mentioned by you callback.
