    copied!<p>I have a Kiwi test performed. Once in 4 runs it raises EXC_BAD_ACCESS exception. What could be the cause of this?</p> <p>It stops in the middle of first asynchronous test with <code>expectFutureValue</code> invoked. What could go wrong? This is the test:</p> <pre><code>SPEC_BEGIN(NetworkTest) describe(@"The call to the external service", ^{ context(@"context", ^{ __block id origin = nil; __block int x = 0; __block AFJSONRequestOperation *operation; beforeEach(^{ /* [OHHTTPStubs addRequestHandler:^OHHTTPStubsResponse*(NSURLRequest *request, BOOL onlyCheck){ return [OHHTTPStubsResponse responseWithFile:@"test.json" contentType:@"text/json" responseTime:1.0]; }]; */ origin = nil; NSURLRequest* request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://httpbin.org/ip"]]; operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) { origin = [JSON valueForKeyPath:@"origin"]; x = 1; } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) { // no action origin = @"no"; }]; [operation start]; }); afterEach(^{ origin = @""; operation = nil; }); it(@"should be not nil", ^{ [[expectFutureValue(origin) shouldEventuallyBeforeTimingOutAfter(3.0)] shouldNotBeNil]; }); it(@"should set x to 1", ^{ [[expectFutureValue(theValue(x)) shouldEventuallyBeforeTimingOutAfter(3.0)] equal:theValue(1)]; }); it(@"should return an IP address", ^{ [[expectFutureValue(origin) shouldEventuallyBeforeTimingOutAfter(3.0)] equal:@"10.1.48.223, 194.50.118.230" ]; }); }); }); SPEC_END </code></pre> <p>Once in 4 runs it raises EXC_BAD_ACCESS exception.
