Has anyone gotten profiling to work under XCode? Running and debugging works perfectly, but profiling causes the Instruments app to crash instantly. Any ideas?

I can run memory leak checking in profiling successfully. (Xcode 4.2.1, OS 10.7.3, cocos2d-x 0.12.0)

Instruments crashing during iOS apps profiling is quite a common problem, I founded no clear solution, or, at least, clear definition of reason. Though there is a lot of various particular solutions can be found in the web, neither of them works for me. Instrument just started to crash in one day, and returned to normal state next morning. :/
