Yesterday I encountered a very strange bug/feature in Xcode. I just couldn’t run any application in Release configuration anymore. I always got “The Debugger has exited with status 1.” in the run-log. In debug configuration they worked, without Xcode they worked, in gdb they worked, but as soon as I tried to start them in Xcode in Release configuration it didn’t work. Not even a fresh new Project would work.
I tried removing the prefs but that didn’t help. But it seemed to be user-dependent. I could run my Projects in Release configuration when I logged in as another user.
This morning I saw the “GDB Log” setting in the Debugging Prefs. I activated them and compared the logs of Debug configuration and Release configuration. And this really showed the bug. I had a binary of a System-Framework in my Release folder and instead of the system-version it linked the application to this binary. To my bad it was a binary from a different mac, which is still running 10.4. This made the app exit right when it was started.
The solution was as simple as removing this binary from the Release-folder.
This GDB log is really a lifesaver sometimes!
