is duplicated by:

  • SR-10446 Swift 5 regression: playground/REPL crash around key paths

relates to:

  • SR-10185 Runtime crash using KeyPath: load from misaligned raw pointer
  • SR-10590 Compiler crash with key paths and generics

Issue Description:

This code crashes Playground execution in Xcode 10.2 beta 4 (10P107d)

But works fine in Xcode 10.1.

import Foundation

let strs: [[String]] = [["adfasdf", "adfasf"], ["sdghdgfh", "hjfhgjfg"], ["dfghfgd", "5t345", "sdfsdfs"]]

extension Collection {
    func map<R>(_ keyPath: KeyPath<Element, R>) -> [R] {
        return map { $0[keyPath: keyPath] }
    }
}

let s = strs.map(\.first)
// error: Execution was interrupted, reason: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0).
// The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation.
// In Console: Fatal error: load from misaligned raw pointer


print(s)

Maybe its only Xcode/Playgroud issue, not compiler issue.

Crashes on master too (outside of a playground):

Assertion failed: (isTypeMetadata()), function getDescription, file /Volumes/Data/swift-public/swift/include/swift/ABI/Metadata.h, line 1069.
zsh: abort      ./main

@jckarter, @mikeash, does this look familiar? I don't see anything obviously wrong with Anton's code.

That's a new one for me. I don't get that isTypeMetadata failure (are you suffering from stale-CMake-itis?) but I do get the misaligned load error from the original report. It only happens for me when using the interpreter, though, not when compiling and running. The error happens in _resolveRelativeIndirectableAddress, which in the example I have in the debugger was called with a base of 0x0000000106cfd01c. Not sure where that bogus value is coming from.

Looks like this bug fixed in Xcode 11.3

Also works in Xcode 11.4.
