is duplicated by:

  • SR-7114 REPL hangs for no apparent reason

Issue Description:

in REPL:

1> let arrayPath=\Array<Int>.count
intArrayPath: KeyPath<[Int], Int> = {
  Swift.PartialKeyPath = {
    Swift.AnyKeyPath =
{       _kvcKeyPathStringPtr = nil     }
  }
}
2> [1,2,3][keyPath: arrayPath]
$R0: Int = 3
3> [1,2,3][keyPath: arrayPath] # Crashes, REPL hangs

Alternatively, merely creating a new KeyPath appears to segfault/hang the system:

3b> let anyArrayPath = \Array<Any>.count

Doesn't seem to happen with a normal compiler -> over to LLDB.

This should be fixed in apple/swift-lldb#635
