POWhy do my OCUnit tests fail with "code 138"?

Body
copied!<p>I'm currently trying to learn objective-c using XCode 3.1. I've been working on a small program and decided to add unit testing to it. </p> <p>I followed the steps on the Apple Developer page - <a href="http://developer.apple.com/mac/articles/tools/unittestingwithxcode3.html" rel="nofollow noreferrer">Automated Unit Testing with Xcode 3 and Objective-C</a>. When I added my first test, it worked fine when the tests failed, but when I corrected the tests the build failed. Xcode reported the following error:</p> <blockquote> <p>error: Test host '/Users/joe/Desktop/OCT/build/Debug/OCT.app/Contents/MacOS/OCT' exited abnormally with code 138 (it may have crashed).</p> </blockquote> <p>Trying to isolate my error, I re-followed the steps from the Unit Test example above and the example worked. When I added a simplified version of my code and a test case, the error returned.</p> <p>Here is the code I created:</p> <p><strong>Card.h</strong></p> <pre><code>#import <Cocoa/Cocoa.h> #import "CardConstants.h" @interface Card : NSObject { int rank; int suit; BOOL wild ; } @property int rank; @property int suit; @property BOOL wild; - (id) initByIndex:(int) i; @end </code></pre> <p><strong>Card.m</strong></p> <pre><code>#import "Card.h" @implementation Card @synthesize rank; @synthesize suit; @synthesize wild; - (id) init { if (self = [super init]) { rank = JOKER; suit = JOKER; wild = false; } return [self autorelease]; } - (id) initByIndex:(int) i { if (self = [super init]) { if (i > 51 || i < 0) { rank = suit = JOKER; } else { rank = i % 13; suit = i / 13; } wild = false; } return [self autorelease]; } - (void) dealloc { NSLog(@"Deallocing card"); [super dealloc]; } @end </code></pre> <p><strong>CardTestCases.h</strong></p> <pre><code>#import <SenTestingKit/SenTestingKit.h> @interface CardTestCases : SenTestCase { } - (void) testInitByIndex; @end </code></pre> <p><strong>CardTestCases.m</strong></p> <pre><code>#import "CardTestCases.h" #import "Card.h" @implementation CardTestCases - (void) testInitByIndex { Card *testCard = [[Card alloc] initByIndex:13]; STAssertNotNil(testCard, @"Card not created successfully"); STAssertTrue(testCard.rank == 0, @"Expected Rank:%d Created Rank:%d", 0, testCard.rank); [testCard release]; } @end </code></pre>
