Summary:
The following code compiles fine as Obj-C. When compiling as Obj-C++, it segfaults the compiler.

NSDictionary *dict = @{}
id a = dict[@"one"] ?: dict[@"two"]

Steps to Reproduce:
Install XCode
Try and compile the attached test.mm as follows
clang test.mm

Expected Results:
I'd expect the compiler not to crash

Actual Results:
The compiler segfaults and asks me to file a bug.

Version:
XCode Version 5.0 (5A1412)
Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin12.4.0
Thread model: posix

Notes:


Configuration:
Not configuration-dependent as far as I can tell.

Attachments:
'preprocessed.mm', 'build.sh' and 'test.mm' were successfully uploaded.

test.mm:
//Compiled with `clang test.mm`
//Compiling as test.m -> works fine

#import <Foundation/Foundation.h>

id crashes( NSDictionary *dict )
{
	return dict[@"one"] ?: dict[@"two"];
}
