BP cannot stop program in cygwin environment

Inizia riproducendo il comportamento del punto di interruzione con i file launch.json e tasks.json forniti su Windows e Cygwin, quindi confronta il rilevamento del punto di interruzione nel log del debugger con l'esecuzione continuata riportata. Traccia il punto di ingresso del debugging Cygwin/GDB responsabile dell'arresto sui punti di interruzione. Il lavoro è completato quando il punto di interruzione mette in pausa il programma in modo affidabile e il comportamento di arresto corrisponde a quanto riportato.

Environment

• OS and version:
• Microsoft Windows [Version 10.0.19044.1645]
• VS Code:
• 1.66.2
• C/C++ extension:
• v1.1.0
• OS and version of remote machine (if applicable):
• 3.3.4-2
• GDB / LLDB version:
• gdb 10.2-1
• gcc 11.2.0
• g++ 11.2.0

Bug Summary and Steps to Reproduce

Bug Summary:

• Install latest C/C++ Extension Pack into VS Code
• Install latest Cygwin with gcc, g++
• create a cpp file as follows:

#include <iostream>
using namespace std;
int main(void)
{
    cout << "Hello Wrold!!!" << endl;
    return 0
}

• Add BP in the line cout
• Click "Start Debuging" button on the top-right
• The program will not be stopped and run with "Hello World" in the console
