Objective-C class properties cause SIGILL #243

Closed frankus closed 8 years ago

frankus commented 8 years ago

Declaring a class property in Objective-C:

@property (class, readonly, nonatomic) Foo *shared;

and running sourcekitten (arguments of doc -objc -- -x objective-c -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator10.0.sdk -I /path/to/project) against it fails with a terminated by signal SIGILL (Illegal instruction) error.
