SIGNAL 11 Segmentation fault

[sebthom]

Now that we have recent binaries of HashLink for linux at https://github.com/HaxeFoundation/hashlink/releases/download/latest/hashlink-a505e25-linux-amd64.tar.gz I enabled unit testing for some libraries against HashLink via GitHub Actions.

Unfortunately HashLink crashes repeatedly somewhere in the middle of the tests (involving threading I guess).

SIGNAL 11
Segmentation fault (core dumped)
Error: Process completed with exit code 139.

See https://github.com/vegardit/haxe-concurrent/actions/runs/4015485217/jobs/6897266435#step:15:439

Unfortunately I cannot reproduce this locally. I also tried to run the GitHub workflow locally using https://github.com/nektos/act but HashLink doesn't crash there either.

Any ideas how to get closer to the root of this?

In another run I got this stack trace:

I made some fixes in EventLoop since 4.2.5, maybe try with these applied ?

I tried HL 1.13 with 4.3.0-rc.1+a985681 and still get Segmentation faults. The issue seems to be related to std/hl/_std/sys/thread/Thread.hx

I'm running into the same issues with github action runner on ubuntu running the latest hashlink. Is there a version you are reverting to until it is fixed @sebthom ?

[sebthom]

@PXshadow no, I am marking the test step with Hashlink as "continue-on-error: true" and rely on other targets (neko/cpp/jvm) for the time being. But I feel the issues got worse as of HashLink 1.13

[PXshadow]

I have a reproducible occurrence of this issue.

commands:

haxe build.hxml

I've just had the exact same error and stackstrace as sabthom

After I run the update function below, a few ms later I receive the stacktrace above.
