Issue Description:

Can compile and archive my project in xCode 8.2, no errors no warnings. After installing xCode 8.3.x can compile without any errors or warnings, run and debug it in simulator.
But when I'm trying to archive it I'm getting:
Swift Compiler Error: Command failed due to signal: Segmentation fault: 11.

Tried to clean the cashes, delete files from Library\Developer\Xcode\DerivedData directory, nothing helps. The only workable solution for now is to develop and debug in xCode 8.3.2, deploy in xCode 8.2.

There's no backtrace at all in the attached log, which implies infinite recursion in the compiler. Can you share your project with us, either here or at bugreport.apple.com?

Comment by Michael Belmont (JIRA)

Jordan,
Thank you for such a quick replay, the project what I’m working on is under enterprise license and I cannot share whole project with you. Unfortunately error didn’t specify any particular file or class what cause this error (at least I don’t see one).
Thank you,
Michael.

[belkadan]

Yep, and since it's a whole-module optimization problem it may not be a particular file that's at fault. @bob-wilson, is there anything we can ask for?

[bob-wilson]

Michael, can you try downloading a recent development snapshot from swift.org and see if the problem is already fixed?

Bob,
I downloaded and installed the Apr. 18 xCode build, what should I do now?

[bob-wilson]

See the "Installation" subsection under https://swift.org/download/#using-downloads

Comment by Michael Belmont (JIRA)

Bob,

With toolchain compiler I got a bunch of warings mostly: "Argument of '#selector' refers to instance method 'LongPress_Action' in 'OrderCell' that depends on '@objc' attribute inference deprecated in Swift 4" and
"'@IBInspectable' attribute is meaningless on a property that cannot be represented in Objective-C".
When I tried to archive I got a different message: "Command failed due to signal: Abort trap: 6", I uploaded new log file.

Thank you,
Michael.
