Did you see my followup?  The vast majority of live systems do not do
that, so we are accomplishing nothing of value by insisting it's a
crash-worthy bug.

I flat out don't agree that "crash on debug builds but it's okay on
production" is a useful way to define this.  I spend way too much
time already on bug reports that only manifest with asserts enabled.
