Question

I\'m on Windows, running GDB on an executable built under MinGW. The program has an infinite loop. I want to find it by hitting Ctrl + C. When I do, both t

CloseHandle(hProcess);

Have a look on the following GDB initialization script, it is required for this to work with MinGW on Windows 7 and later:
