is duplicated by:

  • SR-13338 Cannot use empty array syntax for options for PropertyListSerialization when running as script

relates to:

  • SR-13247 Crash when using enum case as protocol witness

Issue Description:

The code below when saved as bug.swift and run via Terminal using swift bug.swift causes the error at the bottom to be logged rather than the script from being executed.

enum ValidatorError: Error {
    case invalidURLNew(String)
    case networkingError(Error)
}
JIT session error: No symbol covering address 0x0000000000000486


Failed to materialize symbols: { (0x7fd71dd26090, { _got.$ss5ErrorP7_domainSSvgTq, _got.$ss5ErrorP9_userInfoyXlSgvgTq, _got.$ss5ErrorP5_codeSivgTq, _got.$ss5ErrorMp, _$s8Contents14ValidatorErrorOWOe, _$s8Contents14ValidatorErrorOWOy, _symbolic ______p s5ErrorP, _symbolic _____ 8Contents14ValidatorErrorO, _$s8ContentsMXM, _$s8Contents14ValidatorErrorOMa, _got.$ss5ErrorP19_getEmbeddedNSErroryXlSgyFTq, _$s8Contents14ValidatorErrorON, _$s8Contents14ValidatorErrorOs0C0AAMc, _$s8Contents14ValidatorErrorOMn, ___swift_memcpy17_8, _main, _symbolic SS }) }

This was found originally in this script https://github.com/SwiftPackageIndex/PackageList/blob/main/validate.swift but the exact code which causes the error appears to change.

The script worked fine with Xcode 12 Beta 1 and 2 but broke when Beta 3 was released.

Unable to reproduce using Playgrounds or via Xcode - only via command line
