Comment 4 NHO 2019-12-27 18:02:24 UTC 
Changing memory initialization from CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL to CONFIG_INIT_STACK_NONE fixed the issue, but this is wrong way to go about that.

The right way would be to ensure that your kernel is built with the same compiler as external modules such as net-vpn/wireguard-modules.
