Description

I got crash when I'm trying to use blocks in objc:

#import <stdio.h>
#import <Foundation/Foundation.h>

int main()
{
    void (^testBlock)(void) = ^{
        NSLog(@"Hello world!");
    };
    testBlock();
    return 0;
}

I assume that it's issue with blocks without capturing because next version of main method works for me 

int main()
{
    int anInteger = 42;
    void (^testBlock)(void) = ^{
        NSLog(@"Integer is: %i", anInteger);
    };
    testBlock();
    return 0;
}
