It's still out there. To be clear, virtually no chips before Week 25 pass the segfault test, a large number of chips afterwards pass the segfault test. AMD clearly either upped their production standards or is binning out the worst chips. But there is still a baseline of chips failing.

(user istockporno, 1726PGT) Presumably this is something that will be fixed in the Zen+ stepping/Pinnacle Ridge (Ryzen 2 - not to be confused with Zen2, which will release in 2019?, likely as the Ryzen 3 series). But for the meantime, be aware that you are absolutely buying silicon with known issues and that you should test it and RMA if necessary, and that there is fixed silicon coming within a couple months here that will probably run significantly faster due to process improvements.
