BIRD 3.3.0 crashes on "birdc show route for 209.24.0.0/24"

[Robert Scheck]

Hello all,

unfortunately, BIRD 3.3.0 as shipped by EPEL 9 crashes at the following:

$ birdc show route for 209.24.0.0/24
BIRD 3.3.0 ready.
Connection closed by server
$ 

Jun  9 18:34:47 kernel: bird[17874]: segfault at 0 ip 0000562a987ed574 sp 00007ffed8687a30 error 4 in bird[562a987a1000+11d000] likely on CPU 18 (core 2, socket 0)

The correct answer of above command should be "Network not found", which it
is on at least BIRD 2.16.

Btw, "birdc show route 209.24.0.0/24 filtered" crashes the same way on BIRD
3.3.0. The correct answer would also be "Network not found".

But as "birdc show route for 1.1.1.1" and "birdc show route for 1.1.1.0/24"
both work fine, this only seems to affect non-existing routes?

Do you need anything else for debugging?
