             Summary: grpc call causes segfault
                 Key: DISPATCH-1776
                 URL: https://issues.apache.org/jira/browse/DISPATCH-1776
             Project: Qpid Dispatch
          Issue Type: Sub-task
            Reporter: Gordon Sim
            Assignee: Ganesh Murthy


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:

{noformat}
Thread 4 "qdrouterd" received signal SIGSEGV, Segmentation fault.
