Swift runtime bug

Hi there!

Has anyone a clue, what this error message means?

import PlaygroundSupport
import Foundation
let c: Float80 = Float80.init(10000.0)
print(c.debugDescription)
/* SWIFT RUNTIME BUG: unable to demangle type of field '_value'. mangled type name is 'Bf80_'
/* 10000.0

Swift Version 4.2, Xcode 10 beta 5

Best regards!

@strike can you file an SR for this on bugs.swift.org? I think just providing the snippet/swift-xcode version as you have done here would be sufficient.

@dcci @xedin spestov says this is something you guys would be interested in.
