Anybody gettting this after migrating to 1.5.0?

after some trial and error I narrowed it down to function subclasses

object UsageItemMapper :
        (TotalUsage, List<Service>, UsageDetailTab, Map<String, Product.Options>?, LoadedSubscriber, Boolean) -> List<UsageItem>() {

    override fun invoke(
        totalUsage: TotalUsage,
        services: List<Service>,

If I make it not extend function, and not override invoke, and just call it some regular name, it works

Looks like this is https://youtrack.jetbrains.com/issue/KT-44013

[Alexey Belkov [JB]]

Try to remove the constructor invocation of function supertype, does it work?

[ursus]

Yes that works! Is this a bug or desired? Error message is rather cryptic

[Alexey Belkov [JB]]

It is a bug (regression in the new JVM IR backend), we plan to release a hotfix in 1.5.10. Eventually, such code will probably be forbidden by the compiler, see https://youtrack.jetbrains.com/issue/KT-46344

great, thanks
