Compile the following with:

% clang -framework Foundation -fobjc-arc -o ac autoreleasing-capture.m

Running this will often result in a segfault (but sometimes works, depending on ordering and that stuff). Expected result: Don't segfault, OR compiler should generate a warning if it's invalid to capture an __autoreleasing variable.


The code:

#import <Foundation/Foundation.h>

int main(int argc, const char *argv[])
{
    @autoreleasepool {
        __autoreleasing id thingy = [NSString stringWithFormat:@"Hi %@", @"folks"];

        dispatch_async(dispatch_get_global_queue(0, 0), ^{
            NSLog(@"thingy: %@", thingy);
            exit(0);
        });
    }

    dispatch_main();
    return 0;
}
