mosquitto_connect seems to leak memory when using TLS

[Pehoh]

When using mosquitto_connect() with these functions called before:

• mosquitto_lib_init()
• mosquitto_new()
• mosquitto_connect_callback_set()
• mosquitto_message_callback_set()
• mosquitto_publish_callback_set()
• mosquitto_username_pw_set()
• mosquitto_tls_set()
• mosquitto_tls_opts_set()

Valgrind reports me some memory lost (20 bytes definitely lost and 16 bytes indirectly lost).

If I remove the TLS part of my application (mosquitto_tls_set() and mosquitto_tls_opts_set()) and remove the TLS configuration on the broker, the memory lost fall to 0 byte.

Configuration:
Mosquitto 1.5.3, TLS v1.2, server certificate only.

Are you aware of this?

Could you provide the two valgrind traces please?

[Pehoh]

I'm sorry but I'm not able to reproduce the memory lost by isolating the mosquitto calls only. I think it is part of my application. I still don't know why it is not leaking when I disable the TLS. I will try to extract a sample code in the next days.

Maybe related to #592 which was fixed in 1.5.4?

I can't reproduce this myself, and you were having trouble doing the same, plus this has been dormant for a while so I'm going to close this issue. If it is still a problem please reopen and provide details.
