This is equivalent to stopping your executable immediately after it crashes but before the process is terminated and issuing the Run Attach To Process command.

In Snow Leopard Xcode preemptively starts the gdb debugger every time you launch your application from within Xcode so in effect it s already attached. The Additional Directories to Find Source File In pane lists the paths to where the debugger can find the source file used to build the executable being debugged. Normally you don t need to add anything here because Xcode automatically searches all of the source directories in your project. However if you have included source files outside your project or the executable was built from source files that Xcode doesn t know about files in an externally built target for instance add those directories here. You can click the button and type in the path or drag a folder from the Finder and drop it into the list. Selecting an Executable The active executable that you select using the Project Set Active Executable menu is the executable that will be launched when you choose any of the Run or Debug commands. This is typically the product produced by the active target but it doesn t have to be. After selecting a target you can change the active executable to an executable produced by another target or to a custom executable that you ve created. When you switch targets Xcode examines the active executable. If the active executable is the one created for the product produced by the current target and the target you are switching to produces an executable product the active executable is changed to match the new active target.
