Segmentation fault on 3.0.22 and head when doing a request status_check

I've tried doing an upgrade to 3.0.22 (built locally from source), all our tests pass but one with FreeRadius suffering a segmentation fault.
It appears to be when FreeRadius attempts a status_check after getting no response from a server when it's attempting to proxy a request, specifically a request status check, a status-server check does not cause an issue and neither does no status check.
(fulradiusd -X output at end of email)
(0) Proxying request to home server 127.0.0.1 port 5555 timeout 2.000000

Segmentation fault (core dumped)
The minimal configuration I've used to replicate the issue on top of the out of the box configuration, just adding to proxy.conf:
home_server home_server_bt {
type = auth
ipaddr = 127.0.0.1
port = 5555
secret = secret
response_window = 2
status_check = request
username = "test_user_please_reject_me"
password = "this is really secret"
check_interval = 30
num_answers_to_alive = 3
}
home_server_pool auth_pool_bt {
home_server = home_server_bt
virtual_server = virtual_server_bt
}
realm bt.com {
auth_pool = auth_pool_bt
}
And an empty virtual server in sites-enabled:
server virtual_server_bt {
}
I've tried to rule out anything environmental by trying this on builds on Ubuntu and Oracle Linux. I've also tried a build from head of the v3.0.x branch.
