After bumping to the JS IR Compiler (and Kotlin 1.5.31) I'm running into a compiler error that I can't seem to track down when compiling a specific test compilation.

All of my main compilations, and all of my other test compilations seem to compile and run just fine.

Does this look like a known issue to anyone? Does anyone know if there's a logfile lingering somewhere that might give me some more details?

Truncated stacktrace below -- full stacktrace in thread.

> Task :my-module:compileTestDevelopmentExecutableKotlinJs FAILED
e: java.lang.NullPointerException
	at org.jetbrains.kotlin.ir.backend.js.transformers.irToJs.IrElementToJsStatementTransformer.visitCall(IrElementToJsStatementTransformer.kt:132)
	at org.jetbrains.kotlin.ir.backend.js.transformers.irToJs.IrElementToJsStatementTransformer.visitCall(IrElementToJsStatementTransformer.kt:20)

* What went wrong:
Execution failed for task ':my-module:compileTestDevelopmentExecutableKotlinJs'.
> A failure occurred while executing org.jetbrains.kotlin.compilerRunner.GradleCompilerRunnerWithWorkers$GradleKotlinCompilerWorkAction
   > Internal compiler error. See log for more details

The bugs are tricky, the best approach is usually to upgrade all your dependencies to 1.5.31

[ankushg]

Hm, I'm using the latest version of all my dependencies…. maybe I'll downgrade back to 1.5.30 for now to make sure that the compiler error is gone and then wait it out

[ankushg]

Getting the same stacktrace on 1.5.30, and all my dependencies are up to date there 😕

[ankushg]

Is there anywhere I should be looking for a log file? When I encountered a compiler crash with Kotlin Native, I was able to look at logs in ~/Library/Logs/DiagnosticReports/test.kexe_*

[andylamax]

I am assuming you have cleaned your build already, and rebuild.

Also, please confirm if task compileKotlinJs success and compileTestDevelopmentExecutableKotlinJs still fails. Majorly that is usually due to a linking issue

[ankushg]

Definitely cleaned/rebuilt multiple times using both 1.5.31 and 1.5.30

I'm able to run compileKotlinJs , compileProductionExecutableKotlinJs , and compileDevelopmentExecutableKotlinJs

I'm not able to run compileTestDevelopmentExecutableKotlinJs or compileTestProductionExecutableKotlinJs

[ankushg]

Any tips on how to track down what might be causing a linking issue?

[rnett]

That's a NPE in the compiler, it's probably not anything you're doing, just a compiler bug

[rnett]

Best bet is a youtrack issue for anything from org.jetbrains.kotlin packages. You might be able to run on a newer JVM to get what variable is null and look at the code to figure out what's going on, but it's not easy

[ankushg]

I tried moving around JVM versions, with no luck.

I did notice that 1.6.0-M1 was tagged less than 10 hours ago though, so I tried using that.

Issue still there 😞
