I don't fully understand your question. From my side, I just should get a tree
kind of thing.

I sent you the wrong response in the bug sorry. I'm getting this:
qtc.dbg.dapengine: "Content-Length: 186\r\n\r\n{\"request_seq\": 36, \"type\":
\"response\", \"command\": \"variables\", \"body\": {\"variables\":
[{\"variablesReference\": 0, \"name\": \"this\", \"value\":
\"0x7fffffffdab8\"}]}, \"success\": true, \"seq\": 87}"

So I'm getting "this" and the variablesReference is 0. So it means that it has
no children. But it has "i". So I should get "this" with variablesReference e.g
1. And then I could request variables for this variablesReference like this:
"Content-Length:
86\r\n\r\n{\"arguments\":{\"variablesReference\":1},\"command\":\"variables\",\"seq\":50,\"type\":\"request\"}"
And should get a list with "i" inside.

So for gdb without DAP it sends it this way("i" is a child of "this").
