MME crash when received pdn request with ipv6
When I use Huawei Mobile Wifi to connect, it will send the second pdn request which is ipv6, then MME crashed with below print instead of response pdn reject ( I used oai-cn v1 )
mme: /home/sea/mosaic5g/store/snaps/oai-cn/parts/mme/src/src/gtpv2-c/nwgtpv2c-0.11/src/NwGtpv2c.c:487: nwGtpv2cCreateLocalTunnel: Assertion 0' failed. /snap/oai-cn/29/run: line 71: 8072 Aborted (core dumped) $MME_EXEC
echo MME_EXEC_ARGS` "

I tried the disable the IPv6 function in configuration with below steps:
- change IP_CAPABILITY to IPV4 in mme.conf IP_CAPABILITY = "IPV4"; # IPV4V6
- make sure that the pdn_type is IPv4 in oai_db pdn_type = IPv4
And, the UE apn-name is oai.ipv4 which is same as configuraion in pdn (oai_db).
is there any other place to be changed to prevent pdn with ipv6? or any method to prohibit mme crash when received this message?2_pdn_request_7-apn-oai.ipv4.pcapng
