@Dan Gohman hm looks like this build failed on master -- https://github.com/bytecodealliance/wasmtime/runs/501673516?check_suite_focus=true -- which I think is the test you added

bytecodealliance/wasmtime

Standalone JIT-style runtime for WebAssembly, using Cranelift - bytecodealliance/wasmtime

Alex Crichton (Mar 11 2020 at 21:12):

is that a spurious failure you think?

Dan Gohman (Mar 11 2020 at 21:13):

It failed once in the CI on the PR, but then after I started debugging it, it disappeared and started passing.

Dan Gohman (Mar 11 2020 at 21:14):

It looks like the child wasmtime process is failing with a SIGSEGV before printing anything.

Alex Crichton (Mar 11 2020 at 21:14):

Alex Crichton (Mar 11 2020 at 21:14):

I will try to reproduce

Dan Gohman (Mar 11 2020 at 21:22):

It doesn't reproduce for me at all locally; i've only seen it fail in CI

Investigating a spurious test failure I'm able to reproduce this locally on Linux with a script that looks like this: use std::os::unix::prelude::*; use std::process::Command; fn main() { let s...

I couldn't see it locally either until I ran a bunch in parallel

Alex Crichton (Mar 12 2020 at 17:22):

for what may be unrelated reasons CI is failing a lot right now

Alex Crichton (Mar 12 2020 at 17:22):

and github is sort of refusing to give me any logs

Alex Crichton (Mar 12 2020 at 17:22):

I'm at a bit of a loss as to what's going on

fitzgen (he/him) (Mar 12 2020 at 17:35):

I was seeing the same logs issue, but you can still view raw logs, fwiw
