[swift-dev] Crash while compiling a getter

[Pushkar N Kulkarni via swift-dev]

Hello,

 I tried to implement NSOrderedSet.reversedOrderSet with this code:

/*@NSCopying*/ public var reversedOrderedSet: NSOrderedSet {

        return NSOrderedSet.init(array: _orderedStorage.reversed())

}

I'm not sure about the correctness/performance of that implementation, but I see a crash while building Foundation(my local "swift" clone is synced with the master). Here is the stack:

----

37 swift           0x00000000010a2025 swift::SILModule::constructSIL(swift::ModuleDecl*, swift::SILOptions&, swift::FileUnit*, llvm::Optional<unsigned int>, bool, bool) + 581

Is it something already known/reported?  Sorry, I haven't been following much of the conversations on swift-dev.

Thank you!
