Clusterfuzz seems to be inefficient to find DCHECK failures #4417

@ikilpatrick raised the question some time ago, and I'm feeling the same: Has anyone else been finding that clusterfuzz is ineffective in finding DCHECKs these days?

It seems that all automatic clusterfuzz bots build with dcheck_always_on=false. Can clusterfuzz run have a DCHECK enabled bot (e.g. running the automatic jobs? The test cases will be very helpful for debugging and fixing DCHECK failure bugs reported by the crash system.

@letitz WDYT?

Chrome is far from DCHECK clean, though progress has been made in this area. We've thought about enabling DCHECKs, just not very recently :) See https://crbug.com/40281540.
