SR-6846 Swift 4.1 compiler crash with optimization

Issue Description:

After converting AsyncImageView to Swift 4.1, I compiled it with Carthage and realized it crashes the compiler (not in Debug). You can clone the branch on that exact state from the repo or download it directly from here.

Once open, select the AsyncImageView-iOS scheme and compile (I already set it to Release configuration).

Stack trace:

slavapestov · 2018-01-20T00:39:27Z

For once, a bug in LLVM and not Swift!

NachoSoto · 2018-01-20T00:48:39Z

Yay?

vedantk · 2018-01-23T01:22:28Z

@NachoSoto could you provide some more instructions for reproducing this crash? Simply compiling it in Xcode does not work (there's a build error about ReactiveSwift being built already for 4.0.1). Do I need to run a carthage command first? Thanks.

NachoSoto · 2018-01-23T01:24:10Z

Can you try removing derived data? The correct framework is already built in the repo. Make sure you're using the AsyncImageView-iOS schema!

vedantk · 2018-01-23T01:27:36Z

I wiped the derived data in ~/Library/Developer/Xcode, but am still seeing:

Module compiled with Swift 4.1 cannot be imported in Swift 4.0.1: /Users/vk/Desktop/AsyncImageView-swift-4-1-release/Carthage/Build/iOS/ReactiveSwift.framework/Modules/ReactiveSwift.swiftmodule/x86_64.swiftmodule

Should I wipe the Carthage Build directory as well?

vedantk · 2018-01-23T01:29:16Z

Ah, oops, I'm not building with a new enough swift. Sorry for the noise.

NachoSoto · 2018-01-23T01:45:54Z

Oh yeah, I thought you meant the opposite.
Let me know if it's "building" now 🙂

vedantk · 2018-01-23T01:48:06Z

Hm, I'm building with this swift, but it's still not the right version:

/Library/Developer/Toolchains/swift-4.1-DEVELOPMENT-SNAPSHOT-2018-01-18-a.xctoolchain/usr/bin/swift --version
Apple Swift version 4.1-dev (LLVM ef53654946, Clang f7df1e5a04, Swift 831b78c)
Target: x86_64-apple-darwin16.7.0

Do you have a link to a working dev snapshot (from https://swift.org/download/#snapshots)? Thanks again for your help.

NachoSoto · 2018-01-23T01:57:13Z

Are you getting the same error? I built this using the latest snapshot for 4.1

If you need to, you can rebuild dependencies with the following command:

carthage build --platform ios --toolchain {ToolchainID}

vedantk · 2018-01-23T03:14:25Z

Yes, I'm seeing the same error:

Module compiled with Swift 4.0.3 cannot be imported in Swift 4.1: /Users/vk/Desktop/AsyncImageView/Carthage/Build/iOS/ReactiveSwift.framework/Modules/ReactiveSwift.swiftmodule/i386.swiftmodule

I'm using the latest 4.1 snapshot ("Swift 4.1 Development" on this page: https://swift.org/download/#snapshots ), but the ReactiveSwift module included in your package is built with 4.0.3:

I suppose I need to rebuild the dependencies, but I'm not sure how to do that as I'm unfamiliar with carthage. The carthage command you provided doesn't look like it's rebuilding anything:

$ carthage build --platform ios --toolchain XcodeDefault

- - xcodebuild output can be found in /var/folders/nw/6dc3t26s1d721jg_61pvhjg80000gn/T/carthage-xcodebuild.qF3xbC.log
  - Fetching RandomKit

Would it be possible for you to share a package where ReactiveSwift is compiled with the 4.1 snapshot? If I'm misunderstanding your instructions – apologies!

NachoSoto · 2018-01-23T17:52:25Z

I'm happy to help! Is there any chance we can use any form of IM to speed this up? I can help you diagnose why Carthage isn't building.
I think that's going to be more useful than my building everything again, cause by the time I do that there's going to be a new snapshot...

vedantk · 2018-01-23T20:35:29Z

@NachoSoto thanks, feel free to direct-message me on IRC. I'm on the #llvm channel on OFTC as vedantk (https://llvm.org/docs/#irc).

Could you also attach the full swift compiler invocation which crashes? It might rule out a few types of issues.

NachoSoto · 2018-01-24T18:01:53Z

I don't use IRC...
Can you verify that you have the latest version of Carthage? You should have 0.27.0 ($ carthage version).

NachoSoto · 2018-01-26T19:52:05Z

@vedantk okay, now that Xcode 9.3 beta 1 is out, you can test this with that version. I just updated the branch to use that version of the compiler.

If you still need to build by hand, the command I mentioned should work (I don't know if "XcodeDefault" is a valid toolchain though, you need the ID). But again, make sure you have the latest version of Carthage installed.

NachoSoto · 2018-01-26T19:52:15Z

This is what the error looks now?
