Kotlin version: 2.0.0

composeCompiler {
    enableStrongSkippingMode = true // compiles ok if false
}

class ClassWithData(
    var action: Int = 0,
)

@Composable
fun StrongSkippingIssue(
    data: ClassWithData
) {
    val action by data::action
    { action } // compiles ok with @DontMemoize
}

Reassigned to as...@google.com.

The approximate IR generated:

    val action by {
      val action%delegate = data::action
      get() {
        return action%delegate.getValue(null, ::action%delegate)
      }
    }
    %composer.cache(%composer.changedInstance(action%delegate)) {
      {
        <get-action>()
      }
    }

It seems like we are keying based on action$delegate variable which we technically shouldn't have access to. The correct transform is to lift data::action into a local and use it for both delegate and the key.

Marked as fixed.

Fixed with https://github.com/JetBrains/kotlin/commit/d6ac8a50a4eb4ce1c6464cb5103d2d9b04f67019.
