Stack smashing detected

[martinezcp]

Hi,

I have had this gateway working for some years now. No issues until yesterday.
My machine: Linux mqtt 5.4.0-96-generic #109-Ubuntu SMP Wed Jan 12 16:49:16 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
I have a mosquitto broker too.

The error I get:

*** stack smashing detected ***: terminated
[1]+ Aborted (core dumped) ./MQTT-SNGateway

I just downloaded latest version just in case, complied, configured and same error.
I have tried restarting Mosquitto and restarting the whole machine.

Any test I can do to find the root cause of this? There is enough free memory and hard disk space.
