Netopeer2-server crash with 2.2.28 with TLS configuration

[srikanthsubbaramu]

Hi Michal,
we have observed a netopeer2-server crash during tls call home, we wanted to know if this issue is ever seen or encountered, the backtrace points to strcmp_avx on certificate verification in libnetconf tls calls, Attached netopeer2 core and tls_certs used to configure the server.

BT:
