> Running a simple grpc echo (over http2) through the router causes a segfault.
> To reproduce run router with (you can change the ports if desired, just be
> consistent with the server and client):
> {noformat}
> router {
> mode: interior
> }
> listener {
> host: 0.0.0.0
> port: amqp
> authenticatePeer: no
> saslMechanisms: ANONYMOUS

> httpListener {
> host: 0.0.0.0
> port: 9090
> address: foo
> protocolVersion: HTTP2
> }
> httpConnector {
> host: 127.0.0.1
> port: 8080
> address: foo
> protocolVersion: HTTP2
> }
> log {
> module: HTTP_ADAPTOR
> enable: trace+
> }
> {noformat}
> Then run grpc server with podman (or docker):
> {noformat}
> podman run -it -p8080:9000 quay.io/mhausenblas/yages:0.1.0
> {noformat}
> Then run grpc client, again with podman (or docker):
> {noformat}
> podman run -it --network=host quay.io/mhausenblas/gump:0.1 grpcurl
> --plaintext 127.0.0.1:9090 yages.Echo.Ping
> {noformat}
> I see segfault with following backtrace:
