Issue Description:

When building this project (https://github.com/mluisbrown/SignUpDemo) ) on the swift-bug-report branch the Swift 5.1 compiler has a Segmentation fault: 11 error and compilation fails. I have also attached a ZIP of the project to the ticket.

Here is the stack dump from the Xcode log:

Comment by Michael Brown (JIRA)

The issue seems to be related to using @published with a generic type. If I remove @published from the state declaration the segfault goes away.
