Xcode 5.0.1 iOS 7.0.3 Error with instruments command line tool-Collection of common programming errors

I also encounter this issue on Xcode 5.0.1, instruments doesn’t work even start from UI but instruments works fine with Xcode 5.0

After some investigation, I found that when instruments is starting, the scriptAgent in iPhoneSimulator SDK crashes.

So I replaced iPhoneSimulator7.0.sdk with the one in Xcode 5.0, then this issue is solved. But I am not sure whether this replacement has any side effect.
