Hello! When bumping a project from Kotlin 1.3.60 to 1.5.10, the compiler seems to be erroring out with a java.lang.OutOfMemoryError. What can I do to analyze this further?

[Simon Kågedal Reimer]

Ok, it seems giving it some more max heap space by adding this to gradle.properties worked:

org.gradle.jvmargs=-Dkotlin.daemon.jvm.options="-Xmx1g"

Still probably worth reporting a bug at http://kotl.in/issue, compiler OOMs are bad

[rnett]

A repo project is the best thing you can give them, if it's not private

[Simon Kågedal Reimer]

Unfortunately I can't, it's a private project... So I'm not sure how I can give them any useful reproducable info? I wasn't able to nail it down to any specific code.

[Simon Kågedal Reimer]

In some cases, I got a stack trace for a specific class, and then I commented out all the code in that, but still got OOM – but with no stack trace...

[rnett]

Yeah, I'm not sure how much good it'll do in that case, but it can't hurt. There might be diagnostics you can run, too, but I don't know of any off the top of my head.

[Simon Kågedal Reimer]

Right! Maybe if I report the issue, relevant person will tell me what diagnostics to run.

[Simon Kågedal Reimer]

Seeing some other similar issues, one seems to have attached a hprof – how would I get that...?
