Component used: Jetpack Compose 1.1.0-beta04, Kotlin 1.5.31

I've been experiencing this error for like half a year but usually a full project rebuild helped. But today, suddenly, it started reproducing in a file that I didn't even change and since then I get it every time I build the project and nothing helped me to avoid it since then.

It happens in my open-source Android application so I can easily share the code with you.

Here is the project https://github.com/K1rakishou/Kuroba-Experimental

I have created a separate branch (https://github.com/K1rakishou/Kuroba-Experimental/tree/kotlin-compiler-ir-lowering-bug) where it reproduces 100% of the time for me. Just clone it, switch to kotlin-compiler-ir-lowering-bug build it and it should fail during the compile<flavor-name>DebugKotlin step.

Kotlin compiler version is 1.5.31, tried updating to 1.6.0 but it didn't help. Tried to set useIR flag to false but it didn't help. I'm also using Jetpack Compose (1.1.0-beta04) but the class where the issue occurs does not use Compose.

This issue on Kotlin tracker with more information: https://youtrack.jetbrains.com/issue/KT-46000

They suggested to create an issue here as well since it seems to be the Jetpack Compose compiler plugin issue.
