That might be harder to do for optimised code, where there isn't necessarily a direct correspondence between individual source lines and executable code. IIUC Visual Studio will only debug unoptimised code, gcc doesn't have the same distinction between "debug build" and "release build" - you can debug optimised code. It would also need more integration between gcc and gdb than currently exists.
