maskit opened a new issue, #9857: URL: https://github.com/apache/trafficserver/issues/9857
ATS master crashes while handling this request below. ``` $ curl -kv -d @~/tmp/8k --http2 -H "Expect: 100-Continue" https://127.0.0.1:8443/httpbin/post ``` Removing these 2 lines works for the crash, but I'm not sure if we can really remove those. The lines were added by the PR for H2-to-Origin. https://github.com/apache/trafficserver/blob/9909da8b5621ac85f0a474527cf7fd58a03b1ff0/proxy/http/HttpTunnel.cc#L995-L996 ``` * thread #3, name =
