[ShreckYe]

Describe the bug
Calling an expect/actual function with adefault arguments and a Composable argument throws a NoSuchMethodError during desktop (JVM) run and fails to build with an AssertionError on JS.

Affected platforms
Select one of the platforms below:

• Desktop
• Web (K/JS) - HTML based API
• Possbly others too but I didn't test all of them

Versions

• Kotlin version*: 1.8.0
• Compose Multiplatform version*: 1.3.0
• OS version(s)* (required for Desktop and iOS issues): Ubuntu 22.04.2 LTS
• OS architecture (x86 or arm64): x86-64
• JDK (for desktop issues): OpenJDK Runtime Environment (build 17.0.5+8-Ubuntu-2ubuntu122.04)

Thanks!

We had the similar issue in the past. But it seems the bug is not complitly fixed.

This is still reproducible:

// commonMain
expect fun itemInternal(
    key: Any? = null,
    content: @Composable () -> Unit
)

// desktopMain
actual fun itemInternal(
    key: Any?,
    content: @Composable () -> Unit
) {

}

fun main() = singleWindowApplication {
    itemInternal {

    }
}

If we add @Composable to itemInternal, the issue dissapears.

Fixed in 1.4.0 if used with kotlin 1.8.20
