Segmentation fault in stats.c

Hey there just upgraded to fedora 32 and kresd started crashing in the following line:

https://gitlab.labs.nic.cz/knot/knot-resolver/-/blob/v5.0.1/modules/stats/stats.c#L496

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff6ba20fe in stats_init (module=0x5555555d6170) at ../modules/stats/stats.c:496
496			sa->sa_family = AF_UNSPEC;

(gdb) l
491		if (array_reserve(data->upstreams.q, UPSTREAMS_COUNT) != 0) {
492			return kr_error(ENOMEM);
493		}
494		for (size_t i = 0; i < UPSTREAMS_COUNT; ++i) {
495			struct sockaddr *sa = (struct sockaddr *)&data->upstreams.q.at[i];
496			sa->sa_family = AF_UNSPEC;
497		}
498		return kr_ok();
499	}
500


(gdb) print sa
$2 = (struct sockaddr *) 0x0	

(gdb) print data->upstreams
$3 = {q = {at = 0x5555555efba0, len = 0, cap = 1024}, head = 0}

Why does sa evaluate to 0x0, did something change in regards to memory allocation for the used ring-buffer? I can't quite figure out what's going on here, any help is appreciated.
