Ryzen is crappy? Are you a troll?

Yes. No. You don't seem to own a Ryzen. I do.

Let me give some brief information about my current computers. One Ryzen 7 1700, right now showing 516 valid tasks and 60 errors. And one FX-8320E, 67 valid and 1 error. I can assure you the Ryzen behaves exactly as planetclown describes. Either the application crashes outright with a segmentation fault, or the C library kills it because it detected an invalid pointer, this way preventing a possible segfault. If you think about it there must also be cases where an invalid pointer goes unnoticed but doesn't cause a segfault. The result could be anything. I wouldn't rely on a Ryzen for something important, let's hope this project's validator is good. If you dig through the project's host list you'll find more Ryzens showing these symptoms, the most obvious running Linux, but also some Windows hosts with a high number of access violations that could be related.

Also as planetclown describes, the errors don't seem to happen with the new Rosetta application and not at other projects, so you could be tempted to dismiss this as an application error in Rosetta Mini. But there's at least one other example of spontaneous segfaults on Ryzens. Search for "kill_ryzen" or "marginality error" and you'll find many reports on Ryzens segfaulting in a particular use case: massive parallel compiler runs on Linux. An extreme scenario, but not unrealistic, and there's no excuse for simply crashing. People there claim you're safe if you don't do that kind of thing, but without arguments, and Rosetta proves them wrong.

So there's at least two completely unrelated cases of several Ryzens segfaulting out of the blue and no valid reason to assume thats's all. In other words, those things can unpredictably crash for unknown reasons and if they don't crash you still can't trust the results. Crap.

Rosetta Mini v3.78 x86_64-pc-linux-gnu
Rosetta Mini v3.78 i686-pc-linux-gnu

I've seen it on Lubuntu and Linux Mint (both Ubuntu 16.04/Xenial) along with BOINC 7.6.31. Link to computer.

The first error is glibc detected with free(): invalid pointer
