1.5.1 segmentation fault

[AlexIT-FT]

I used fort 1.4.2 for a long time, now tried to replace it with 1.5.1 ... and segmentation fault
The same , running as a service , or manually with --configuration-file
The same , with my old config.json and with the fresh-new one (almost empty) from deb file.

The OS is DEBIAN 10.10
Linux rpki 4.19.0-17-amd64 #1 SMP Debian 4.19.194-3 (2021-07-18) x86_64 GNU/Linux

This is from syslog

Installed 1.5.0 and all is working, with no issues.

Ok, found it. It' a null pointer. It happens when server.address is undefined in the configuration.

Will upload a patch shortly. You can also work around the problem by declaring server.address.
