Hmm, that's strange, I'm not able to reproduce this. Is this on an EC2 instance? Can you provide the output of /proc/cpuinfo if possible?
This is just on my laptop, a Dell XPS 9370.

I noticed that this happens on nightly Rust -- is that what you were using by any chance? I'll look into it further to see what the root cause is, but on my machine these tests work okay on the latest stable version of Rust.
I think I was running nightly
, yes. But now using the latest master and latest nightly the problem has fixed itself. Strange but good!
Hi, on current master I get a SIGILL while running the test suite. Specifically all the tests in
error_tests
are causing the problem. Running Ubuntu 18.04.
