asking for a 5MB payload, I was able to make the go-wolfssl-https-server repro server crash by itself on
an invalid wolfssh free() call. I'm not sure at which layer the bug is, but there is something certainly off.
Unless you have a strong need for pre-shared-keys (which the Go standard library TLS server
does not support; https://github.com/golang/go/issues/6379), I would, like Amnon, also think it
much better to use the standard library's TLS server facilities. Then you won't need to mess with
the go-wolfssh shim or CGO at all.
