Flaky test - objc_nonnull_lie_hack


(Slava Pestov) #1

Hi all,

Is anyone else seeing this? I haven’t seen it in CI, but for me this test fails at random, very rarely too — looks like something is non-deterministic in the optimizer?

I saw this once on Tuesday. I haven’t seen it since then.

Yes, I hit this a couple days ago and attempted to reproduce and couldn’t.

Running it in a loop on another machine doesn’t trigger it, so I’m thinking it might be a random variation in how the standard library is built?

Dmitri tracked it down and has a fix for it, and then I had a complaint about his fix, and then I didn't get back to it. :slight_smile:

(Slava Pestov) #6

Oh, cool!

The change looks good to me. It’s a bit of a hack but less so than -enable-source-import. There are annoying differences in behavior between -enable-source-import and the real module loader, and this is made worse by the fact that so many tests use -enable-source-import so we’re effectively testing a debug-only code path. I’d like to just rip it out one day.
