Strangest thing happening to me right now: GDB seems to launch after the app does.

Output in xcode terminal window looks like this:

As you can see, Xcode thinks the session start twice, but this is, and I'm 100% sure, the result of hitting "Build and Run" once, and that never failed me thus far.

What (am I)/(is Xcode) doing wrong?

PS. I noticed there's a setting "Start executable after GDB launches" in the Debugging tab of the "Executable Info"-screen, but that is checked (changed nothing there by the way, this behavior suddenly started).

PPS. Killed iPhone Simulator before killing App from xcode, normally gave me a "Terminating in repsonse to Switchboard.." now it said this (Full session output):

This is the way that debugging works for iPhone apps, both on the device and simulator. Note the two parts:

2010-02-15 18:57:35.822 CPPlayer[2890:207] CPLanguageManager.m:26 Initializing LanguageManager

The "2980" is the process ID (pid) of the running app.

Attaching to process 2890.

That's gdb attaching to the already-launched app.
