Unable to pause execution with root gdb

Type: Debugger

Describe the bug

• OS and Version: Ubuntu 16.04.6 LTS
• VS Code Version: 1.38.1
• C/C++ Extension Version: 0.25.1

We needed to debug a program which needs root privileges to be run. In order to do this a added a wrapper to gdb to lauch with sudo and without password.

#!/bin/bash
sudo gdb "$@"

When we launch a program with the wrapped dbg(set on miDebuggerPath), we are not able to pause the execution of the program or add and stop on a breakpoint.

Although, when the breakpoint is already set before lauching the debugger, it will pause there and we are able to step through the code and also set new breakpoints. After removing the breakpoints and continuing execution we are again unable to pause execution.

Inizia riproducendo il problema con il wrapper sudo gdb configurato tramite miDebuggerPath su Ubuntu. Confronta il comportamento della pausa e dei breakpoint prima e dopo la ripresa dell'esecuzione; il lavoro è concluso quando è possibile mettere in pausa l'esecuzione e aggiungere breakpoint in modo affidabile durante il debug di un programma che richiede i privilegi di root.
