It’s perfectly safe to use realloc. It is the way to reallocate memory in a C program. However you should always check the return value for an error condition. Don’t fall into this common trap: p = realloc(p, new_size); // don’t do this! If this fails, realloc returns NULL and you have lost access to … Read more
It’s important to be precise in the use of the term ‘memory leak’ with respect to Java. In Java, a memory leak happens when your code holds a reference permanently, so that some object is never garbage collected. Failing to close a stream is not a memory leak in this sense. Streams that have native … Read more
In past versions of the JDK, the implementation of the substring method would build a new String object keeping a reference to the whole char array, to avoid copying it. You could thus inadvertently keep a reference to a very big character array with just a one character string. Here’s an example of a bug … Read more
I’ve had the same problem, with a lot of the same symptoms: pointer being freed was not allocated error upgraded to Xcode 3.2 error happening in code for images If I change the build target to 3.1, the errors in the simulator go away. If I run the code on the device, the errors don’t … Read more
As strange as it may be, it seems that the memory leak only occurs if you don’t do anything with the search results. Modifying the code in the question as follows does not leak any memory: using (var src = mySearcher.FindAll()) { var enumerator = src.GetEnumerator(); enumerator.MoveNext(); } This seems to be caused by the … Read more
Regarding memory consumption Memory leaks in JavaScript are usually ignored except when they turn into browser memory leaks (that is, even after the user navigates away from the page, the memory continues allocated and there’s no way to free it). The reason for this is that while your web application may have some memory leaks, … Read more
You are leaking the dialog. You need to call pDialog.dismiss(); in the onPostExecute() method of the async task. You should also put… if(pDialog != null) pDialog.dismiss(); in your onPause() method of the activity on the main thread. This will make sure the window is not leaked, even if your application loses the foreground while doing … Read more
I have found out the following: If you change your RAF function into two “ping-pong” like functions, you get alot less garbage. You can’t avoid the first initial “big GC”, but after that you see only minor GCs of about 50kb instead of 700kb-1mb GCs. The code will look like this: <script type=”text/javascript” charset=”utf-8″> window.frameA … Read more
See this answer. It seems that MySQL driver should be in {$TOMCAT]/lib shared between applications. Check that you are not including it with each application. At least it worked for me and I have been able to remove the warning. If you are using Maven mark the dependency as provided. UPDATE: root cause is that … Read more
It may be relevant that Perl never gives memory back to the system by itself: It’s all up to malloc() and all the rules associated with that. Knowing how malloc() allocates memory is important to answering the greater question, and it varies from system to system, but in general most malloc() implementations are optimized for … Read more
