Status:Open Resolved:
Product:Swift Product Version:swift-600.0.34.4.5
Classification: Reproducible:Always
 
Steps to Reproduce:
Using Swift with the following code: 
var explicitOptional: Any!
var anotherExplicitOptional: Any!

if explicitOptional && anotherExplicitOptional {
        // segfault
}


Expected Results:
The expected result should be an evaluation of the expression explicitOptional && anotherExplicitOptional returning true if both of the variables have values or false if any is empty.

Actual Results:
The actual result is a segmentation fault when compiling (a crash of Xcode when using playground) due to a segmentation fault, here's the error I'm getting:
1.	While emitting IR SIL function @top_level_code<unknown>:0: error: unable to execute command: Segmentation fault: 11
<unknown>:0: error: swift frontend command failed due to signal (use -v to see invocation)

(The complete stack trace is attached to this report)


Version:
Xcode 6.0 6A215l Swift 1.0 (swift-600.0.34.4.5)
