  • SR-11059 Abort 6: Property wrapper with default value in initialiser

is duplicated by:

Issue Description:

Swift compiler crashes after adding default value to property wrappers initializer argument

This works fine:

@propertyWrapper
struct Wrapper<T> {
  let wrappedValue: T

  init(wrappedValue: T, argument: Int) {
    self.wrappedValue = wrappedValue
  }

}
class C {
  @Wrapper(argument: 0) var prop = 0
}

However, this crashes:

@propertyWrapper
struct Wrapper<T> {
  let wrappedValue: T

  init(wrappedValue: T, argument: Int = 0) {
    self.wrappedValue = wrappedValue
  }
}

class C {
  @Wrapper var prop = 0
}

Stacktrace:

1.  While emitting IR SIL function "@$s10Playground1CCACycfc".

Doesn’t crash on master - this was fixed a while ago (will dup it when I find the other SR)
