Statistical Defect Detection?

Okay, it's not quite the right place for this, but I'm stumped and many of you keep tabs on this kind of stuff.

A long time ago I ran into a paper on something I remember being called "statistical defect detection", wherein some clever people wrote software to record which branches were taken leading up to a crash and used those to determine, statistically, which lines of code were most likely to be responsible.

I can't find it any more. Can anyone else remember it? Maybe you can help me find it?

Sounds like CBI to me

Check here or look at Prof. Liblit's papers on the matter.


That's exactly it. Thank you!
