ANDAND 条件应该有一个"如果为真，则为假"

Question

我在编译以下代码时遇到问题：

@Composable
fun getWallethColors()= KotprefSettings.getNightMode().let {
if ((it == MODE_NIGHT_FOLLOW_SYSTEM && isSystemInDarkTheme()) || it == MODE_NIGHT_YES)
darkColors()
else
lightColors()
}

它抛出以下错误：

有趣的是，当我把它重写为：

fun getWallethColors(isSystemDark: Boolean) = KotprefSettings.getNightMode().let {
if ((it == MODE_NIGHT_FOLLOW_SYSTEM && isSystemDark) || it == MODE_NIGHT_YES)
darkColors()
else
lightColors() 
}
@Composable
fun getWallethColors() = getWallethColors(isSystemInDarkTheme())

它编译得很好。我是喷气背包创作的新手，想知道我是做错了什么，还是这是一个bug。

Answer 1

这是一个错误。请在https://issuetracker.google.com/issues/new?component=612128

如果编译器抛出：e: org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error，则(根据定义(它始终是编译器级别的错误。
