Crash when compiling ekrich/sconfig #7175
Comments

Thanks for the bug report, I think there is a higher chance of having someone looking into it if it can be minimized into a self contained example. |

I will try and produce a minimization. |

Here is reproducer that produces an error which may be the underlying cause of the crash. This obviously compiles in object foo {
def main(args: Array[String]): Unit = println("Dotty")
import java.net.URL
import java.util.List
trait ConfigOrigin {
def description: String
def filename: String
def url: URL
def resource: String
def lineNumber: Int
def comments: List[String]
def withComments(comments: List[String]): ConfigOrigin
def withLineNumber(lineNumber: Int): ConfigOrigin
}
trait ConfigValue extends ConfigMergeable {
def origin: ConfigOrigin
//def valueType: ConfigValueType
def unwrapped: AnyRef
def render: String
//def render(options: ConfigRenderOptions): String
override def withFallback(other: ConfigMergeable): ConfigValue
//def atPath(path: String): Config
//def atKey(key: String): Config
def withOrigin(origin: ConfigOrigin): ConfigValue
}
trait ConfigMergeable {
def withFallback(other: ConfigMergeable): ConfigMergeable
}
trait MergeableValue extends ConfigMergeable {
def toFallbackValue(): ConfigValue
}
// no impl
final class SimpleConfigOrigin extends ConfigOrigin {
def comments: java.util.List[String] = ???
def description: String = ???
def filename: String = ???
def lineNumber: Int = ???
def resource: String = ???
def url: java.net.URL = ???
def withComments(comments: java.util.List[String]): foo.ConfigOrigin = ???
def withLineNumber(lineNumber: Int): foo.ConfigOrigin = ???
}
abstract class AbstractConfigValue (val _origin: ConfigOrigin)
extends ConfigValue
with MergeableValue {
override def origin(): SimpleConfigOrigin =
this._origin.asInstanceOf[SimpleConfigOrigin]
}

After #7430, I get Once I change |

Thank-you! |
