The following code produces [Internal Error] org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error on build. I don’t see anything technically wrong with this stripped down code snipped. Am i missing something, or is this actually a compiler bug?
inline fun <T>safe(action: () -> T): T{
try{
return action()
}catch(ex: Exception){
try{
action()
}catch(ignored: Exception){
}
throw Exception("failed", ex)
}finally{
}
}
fun test(factory: () -> Int): Int{
safe {
return factory()
}
}
fun main(args: Array<String>) {
val t = test({ 42 })
println("Hello, $t!")
}try.kotlinlang.org responds with
Can’t get program output
