[defect]: rlm_files parsing: talloc abort: Bad talloc magic value - unknown value

[ErmakovDmitriy]

What type of defect/bug is this?

Crash or memory corruption (segv, abort, etc...)

How can the issue be reproduced?

Start FreeRADIUS v4, commit a163440ae3cf230d47196456a805bb9da796356c with DHCP in sites-enabled and an incorrect files content (see below).
The startup fails.

Content of files:

/etc/raddb/sites-enabled/dhcp - it is enough to trigger files module by adding in Discover section:

recv Discover {
        files_dhcp_host
}

/etc/raddb/mods-enabled/files_dhcp:

files files_dhcp_host {
        moddir = ${modconfdir}/files_dhcp
        key = "%{Client-Hardware-Address}"
        filename = ${moddir}/files_dhcp_hosts
}

The /etc/mods-config/files_dhcp/files_dhcp_hosts must be incorrect (trailing commas):

# DHCP Static IP Addresses

# Configuration for IP 10.8.0.10
00:50:56:11:22:33
  Hostname := hostname1.example.com,
  #Your-IP-Address := 10.0.0.10

# Configuration for IP 10.0.0.11
b0:a8:6e:44:55:66
  Hostname := hostname2.example.com,
  #Your-IP-Address := 10.0.0.10


# Configuration for IP 10.0.0.12
b0:a8:6e:55:33:11
  Hostname := hostname3.example.com,
  Your-IP-Address := 10.0.0.12
