The _BLOCK_TYPE_IS_VALID assertion gets fired, when you overwrite the header of an block allocated by new. This happens when you slice objects, use dead objects, etc. You should have a look at your complete code, and try to work from the data you have in your debugger. This short code snippet contains several ‘curious’ usage … Read more
Don’t use if(Dispatcher.CurrentDispatcher.Thread == Thread.CurrentThread) { // Do something } Dispatcher.CurrentDispatcher will, if the current thread do not have a dispatcher, create and return a new Dispatcher associated with the current thread. Instead do like this Dispatcher dispatcher = Dispatcher.FromThread(Thread.CurrentThread); if (dispatcher != null) { // We know the thread have a dispatcher that we … Read more
In JUnit4 the exception (actually Error) thrown by a JUnit assert is the same as the error thrown by the java assert keyword (AssertionError), so it is exactly the same as assertTrue and other than the stack trace you couldn’t tell the difference. That being said, asserts have to run with a special flag in … Read more

Use org.junit.Assert‘s method assertArrayEquals: import org.junit.Assert; … Assert.assertArrayEquals( expectedResult, result ); If this method is not available, you may have accidentally imported the Assert class from junit.framework.
A compile-time assert in pure standard C is possible, and a little bit of preprocessor trickery makes its usage look just as clean as the runtime usage of assert(). The key trick is to find a construct that can be evaluated at compile time and can cause an error for some values. One answer is … Read more
Assertions (by way of the assert keyword) were added in Java 1.4. They are used to verify the correctness of an invariant in the code. They should never be triggered in production code, and are indicative of a bug or misuse of a code path. They can be activated at run-time by way of the … Read more
