The problem with this is that the user doesn't see what will be executed if a step is taken, which makes the user experience quite annoying. How would the community feel if GDB printed the previous line, instead of current line, when the execution direction is reversed? Sorry if this is the wrong list. It didn't feel like a bug, and I don't have a patch yet, so this felt like the best place to send. -- Cheers! Bruno Larsen
