InvalidMutabilityException: mutation attempt of frozen mu.KotlinLoggingLevel

[benkuly]

When using this library with the new native memory model of native I get the follwing exception:

kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen mu.KotlinLoggingLevel@fa8aa0

Thank you for reporting an issue. See the wiki for documentation and slack for questions.

Thanks for reporting! Any idea how this should be fixed?

[benkuly]

Maybe set kotlin.native.binary.memoryModel=experimental in gradle.properties like described in the migration guide

[oshai]

can you provide a test that will reproduce the issue?

[benkuly]

made one here: https://github.com/benkuly/kotlin-logging-issues-218

[oshai]

thanks! would you like to create a pr out of it or should i?

[benkuly]

Would be cool, when you do it :)

[oshai]

So I think now I am able to reproduce it by adding the experiment flag, and created a PR for that:
#219

I am not sure what is the best approach for fixing it.

[benkuly]

Looks good to me :) Thank you very much!

[oshai]

@benkuly maybe you didn't understand my comment. I am able to reproduce it, but no idea how to fix it.

[benkuly]

Oh sorry, yeah, than you are as far as I was, when I tried to fix it :(

[oshai]

Seems that now (3.0.3) that we're using kotlin 1.7.20 this works fine. Anyway I added a test in #219.
