I have a K/N project that already compiles successfully to JVM. If I run the MacOS tests however, it seems to kill the test.kexe file at some point. Some tests are passing though. Any ideas what could be causing this?

[Artyom Degtyarev [JB]]

Hello! This might be a bug, can you share a reproducer?

[Patrick]

Hey, are you talking about the code that will reproduce this? Do you also need os and/or versions?

[Artyom Degtyarev [JB]]

Yes, I meant the piece of code that we could run on our side . But, as I can see from the thread below, you and Kevin managed to find out the reasons. So, let’s assume that my asking is irrelevant.

[Patrick]

Well I’m not sure we have found them. I have one test that fails but if I comment it out, some tests still fail because the Event Loop was cancelled

[Patrick]

I’m not sure how to interpret that

[Patrick]

kotlin.IllegalStateException: Cannot execute task because event loop was shut down

[Patrick]

This is the error message I get

[Patrick]

And I also couldn’t figure out why that particular Tests leads to a segmentation fault

[Artyom Degtyarev [JB]]

Ok then. If you can reveal some additional details over the testTaskDelay(), I will be able to say something more concrete.

[Patrick]

I figured out what the problem was. The thread reached the end of its lifetime while the coroutine was still running

[Patrick]

If I add a delay to the execution, it works

[Patrick]

Do you know why this is not a problem in the JVM?

[Patrick]

Is there a concept that I am missing. All those tests have passed without issue on the JVM

[Artyom Degtyarev [JB]]

I’m not sure about the reason of it, but I got to mention that “correct Kotlin/JVM code” is not a synonym for “correct Kotlin common code”.

[Patrick]

I think I have the reason for the segmentation fault, it is caused by the function measureTimeMillis

[Patrick]

segmentation fault

[Patrick]

This is enough to cause a segmentation fault

[Artyom Degtyarev [JB]]

I cannot reproduce the error on my side. If it’s possible, please make a small project to work with this issue.
