Originator:rix.rob
Number:rdar://19769111 Date Originated:09-Feb-2015 02:44 PM
Status:Open Resolved:
Product:Developer Tools Product Version:Xcode-Beta (6D520o)
Classification:Crash/Hang/Data Loss Reproducible:Always
 
Summary:
Provide a descriptive summary of the issue.

Steps to Reproduce:
1. Clone this branch https://github.com/robrix/List/tree/swift-1.2b1-crasher
2. Clone the dependencies
3. Open the workspace
4. Build


Expected Results:
I expected the compiler to build successfully, or to error out and tell me why.


Actual Results:
It crashed, apparently while typechecking the analysis function:

1.	While type-checking 'analysis' at /Users/rob/Developer/Projects/List/List/List.swift:54:9



Regression:
This does not crash in 1.1.


Notes:
A very similar function, `either`, in my Either library (https://github.com/robrix/Either) does not crash the compiler.
