swift repl crashed on windows.

[liudonghua123]

I have installed swift on windows following the guide on https://www.swift.org/download/#using-downloads, and I also have configured set SWIFTFLAGS=-sdk %SDKROOT% -I %SDKROOT%/usr/lib/swift -L SDKROOT%/usr/lib/swift/windows according to https://forums.swift.org/t/found-some-solutions-when-troubleshooting-installing-swift-on-windows/44467, https://forums.swift.org/t/compiling-a-simple-hello-swift-on-windows/40534/7, https://forums.swift.org/t/swift-5-4-windows/47841/3.

But the issue is likely to be reported to swift bugtracker as it seems as some swift runtime libraries are simply missed.

[compnerd]

I agree with @asl this is not the right place for reporting this issue. Furthermore, you have already posted on the Swift forums with the same issue, please allow time for people to respond - the Windows port is a volunteer port, people cannot respond immediately.
