variables are not being shown in VSCode but GDB is showing them

the setup is:

  • VSCode running on Windows
  • GDB running on linux
  • the ssh extension is being used
  • process is C/C++

The members of a struct are shown in the variable list but they have no value.

I captured the log of the DAP communication and I can see that the variables are being requested and returned empty:

for example:

{
  "type": "response",
  "request_seq": 58,
  "success": true,
  "command": "variables",
  "body": {
    "variables": [
      {
        "name": "next",
        "value": "",
        "type": "struct cdbtype_ *",
        "evaluateName": "((cdbtype *)0x7408b2eaa3e8)->next",
        "variablesReference": 1012
      },
      {
        "name": "pif_type",
        "value": "",
        "type": "enum pif_types_",
        "evaluateName": "((cdbtype *)0x7408b2eaa3e8)->pif_type",
        "variablesReference": 0
      },

If I check the variables inside GDB I can see their value correctly. Given the DAP shows empty strings I believe the problem might be in OpenDebugAD7.

Happy to collect more info if needed.

Can you get the GDB side logs? You can do that with "logging": { "engineLogging": true } in the VS Code debug config.

I have a log with all the logging enabled (OpenDebug AND MI)... these are the relevant lines (I believe):
