Hello,
The following ruleset causes a segfault:
#! /usr/sbin/nft -f
flush table inet filter
define test1 = {
1.1.1.0/24,
}
define test2 = {
$test1,
2.2.2.0/24,
}
table inet filter {
chain input {
type filter hook input priority 0;
ip saddr $test2 counter;
}
}
Either removing the /24s to make them addresses instead of prefixes, or
including test1 instead of test2, avoids the crash.
Backtrace from valgrind:

Is this the right place to report issues like this?
Kind regards,
