Issue Description:

Attempting to build our codebase with the 1st April master snapshot results in compiler crash. This code compiles and runs fine with toolchain included in Xcode 8.3.1. Not able to quickly provide a concise sample to reproduce but happy to work with team to provide any further info !

Console output:

unexpected storage type that differs from type-of-rvalue

Any chance you can attach your entire project, then? Or if not here in public, would you be willing to file a bug with us at Apple (https://bugreport.apple.com) and attach it there?

@gottesmm, does this happen to look familiar?

gottesmm commented 7 years ago

It may be mine. We really need a reproducer.

swift-ci commented 7 years ago

Comment by Mark Woollard (JIRA)

I'll try and get something to you that reproduces this - hopefully can get down to a relatively small project since the source file that is causing the crash doesn't have too many dependencies. May be a day or two until I can get to it.

swift-ci commented 7 years ago

Comment by Mark Woollard (JIRA)

OK was a lot easier that thought - simple project attached to reproduce crash - note that code dependent on RxSwift 3.3.1 or later (zip includes 3.4) configured via CocoaPods so you'll have to use the workspace file to build.

gottesmm commented 7 years ago

I was able to build with the workspace with the latest released Xcode without issue (as expected, just saying that the workspace build works). I am going to try with a ToT build now.

slavapestov commented 6 years ago

@swift-ci create

gottesmm commented 6 years ago

mlwoollard (JIRA User) I think I forgot to update this bug report that I fixed this bug. Can you try with the latest Xcode and see if it occurs for you just to verify?

swift-ci commented 3 years ago

Comment by Mark Woollard (JIRA)

Just signed in after a long absence - can confirm this is fixed ![]( Sorry for the delay )

swift-ci commented 2 years ago

Comment by Mark Woollard (JIRA)

Have confirmed issue is resolved
