Standard error not printed when using PipeTransport

Type: Debugger

• OS and Version: ( local ) Windows_NT x64 10.0.18363 & ( remote ) Red Hat Enterprise Linux Workstation release 7.4 (Maipo)
• VS Code Version: Version: 1.44.2
• C/C++ Extension Version: 0.27.0

Environment : VSCode from local computer, connection trough remote-ssh to a Linux computer able to run VSCode then using pipeTransport to a dedicated machine to work on, where vscode can't be launch trough remote-ssh ( older os ).

When debugging with pipe transport, message to standard error are not displayed, although received. It's also reproducible with gdb command -exec p printf(stderr,"stderr")

To Reproduce
main.c

#include <stdio.h>

int main(int argc, char *argv[])
{
    fprintf(stdout,"stdout\n");
    fprintf(stderr,"stderr\n");
    return 0;
}

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/a.out",
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "externalConsole": false,
            "MIMode": "gdb",
            "pipeTransport": {
                "pipeCwd": "${workspaceFolder}",
                "pipeProgram": "ssh",
                "pipeArgs": [
                    "dedicated"
                ],
                "debuggerPath": "/usr/bin/gdb"
            },
            "logging": {
                "engineLogging": true,
            }
        }
    ]
}

Steps to reproduce the behavior:

1. Compile the program
2. Launch VSCode debugger
3. Look for lines in the debug console

1: (7622) STDERR: stderr ---------------------> Program printed to stderr, GDB received it
1: (7626) ->^running ---------------------> Didn't display it
1: (7626) ->*running,thread-id="all"
1: (7626) ->(gdb)
1: (7626) ->stdout ---------------------> Program printed to stdout, GDB received it
stdout ---------------------> Did display it

Reproduce el problema con main.c y la configuración pipeTransport de launch.json; después, inspecciona la ruta de salida del depurador en busca de mensajes recibidos por la salida de error estándar. Compara las salidas stderr y stdout mostradas, y considera que el problema está resuelto cuando stderr, tanto de la ejecución del programa como del comando printf de GDB, aparece en la consola de depuración.
