XCode can't resurrect !

This morning I was working but XCode decided it didn't wanted to so it crashed (again)

The stack trace was pretty explicit:

XCode can do a lot of things but apparently not resurrect dead objects !

Surprising fact: I almost rarely experiencec crash on my mac except for IDE's

Apple tends to experiment with Xcode itself more than they do with their other apps. Dogfooding and all that. For instance Xcode became 64-bit and garbage collected back for 10.5, while most Apple apps became 64-bit only for 10.6, and I'm not sure they rewrote many apps to be garbage collected even afterwards, it's more meant for new developments. As a result, I have indeed seen more instability from Xcode than from other Apple applications.
