Subject: Segmentation Fault Issue in FreeRADIUS v3.2.5

Hi!

I hope this message finds you well.

I am writing to report a critical issue we have encountered with FreeRADIUS v3.2.5. When the home server does not respond and a proxy request to the user fails, it results in a segmentation fault.

To reproduce the issue, please add the following configuration:

==========================================================================
radiusd.conf:
client redundant-2 {
    ipaddr = "192.168.1.216"
    secret = "testing1234"
}
==========================================================================
sites-enabled/redundant-radrelay-2:
home_server redundant-2-server {
    type = acct
    ipaddr = 192.168.1.216
    port = 1813
    secret = "testing5678"
    status_check = status-server
    response_window = 5
    response_timeouts = 1
    zombie_period = 20
}

home_server_pool redundant-2-pool {
    home_server = redundant-2-server
}

realm redundant-2 {
    acct_pool = redundant-2-pool
}

server redundant-2-server {
    listen {
        type = detail
        filename = /var/data/redundant2/detail
        load_factor = 30
        track = yes
        unlink_work_detail_keep_limit = 1000
    }
    accounting {
        update control {
            Proxy-To-Realm := "redundant-2"
        }
    }
}
==========================================================================
mods-enabled/redundant:
detail detail_redundant2 {
    filename = /var/data/redundant2/detail
    permissions = 0600
    locking = yes
    detail_size_limit = 1048576
    detail_keep_limit_for_size = 1010
}
==========================================================================

When the RADIUS service is started and an Accounting Start packet is received, it results in a segmentation fault.

It appears that the segmentation fault occurs due to a failure to access "request->packet->code" at the following commit:
https://github.com/FreeRADIUS/freeradius-server/commit/67e58e67f7ba0efaa73cf...

Please find the debug log below for your reference:
