I know the possibilities of basic leak detection for Win32 using the crtdbg.h header, but this header is unavailable in the CE CRT library headers (i'm using the lastest SDK v6.1). Anyone knows how I can automatically detect leaks in a WinCE/ARMV4I configuration with VC 9.0? I don't want to override new/delete for my class hierarchy, I...
I'm implementing a sparse matrix with linked lists and it's not fun to manually check for leaks, any thoughts? ...
While learning different languages, I've often seen objects allocated on the fly, most often in Java and C#, like this: functionCall(new className(initializers)); I understand that this is perfectly legal in memory-managed languages, but can this technique be used in C++ without causing a memory leak? ...
I'm trying to run down a memory leak in a windows forms application. I'm looking now at a form which contains several embedded forms. What worries me is that the child forms, in their constructor, take a reference to the parent form, and keep it in a private member field. So it seems to me that come garbage-collection time: Parent ha...
According to MSDN: Array usage guidelines: Array Valued Properties You should use collections to avoid code inefficiencies. In the following code example, each call to the myObj property creates a copy of the array. As a result, 2n+1 copies of the array will be created in the following loop. [Visual Basic] Dim i As Integer For i...
What is the best tool to detect memory leaks. Both free and not Free. Thanks ...
We have an application with hundreds of possible user actions, and think about how enhancing memory leak testing. Currently, here's the way it happens: When manually testing the software, if it appears that our application consumes too much memory, we use a memory tool, find the cause and fix it. It's a rather slow and not efficient pro...
Hi, I'm having problems allocating and deallocating my memory in a recursive C++ program. So without using an automatic memory management solution, I wonder if anyone can help me resolve the memory leak I am experiencing. The following code essentially explains the problem (although it's a contrived example, please correct any mistakes...
Hi, I'm trying to use the CRT memory leak detection but I keep getting the following message in Microsoft Visual Studio: "Detected memory leaks - skipping object dump." I can never get the it to actually do and object dump. I followed the directions in the Microsoft article on Memory Leak Detection (http://msdn.microsoft.com/en-us/libra...
I have a java.hprof.txt file (automatically generated after an OutOfMemoryError) which I would like to convert to the binary hprof format. Is there any easy way to do this? ...
Currently i am working on a desktop application which consists mathematical analysiss.I am using qt for GUI and project written in c++. When user starts an analysis, i open a worker thread and start a progress bar.Everything is ok up to now, problem starts when user cancels operation.Operation is complex, i am using several functions and...
It appears there is a memory leak in the Status property of the SMO Database class. Using the code below with SQL 2005 SMO libraries works fine, but as soon as you use SQL 2008, the memory leak appears.... Any other good way of getting the database staus in SQL 2008? A quick example that magnifies the problem: private void button...
Perl uses reference counting for GC, and it's quite easy to make a circular reference by accident. I see that my program seems to be using more and more memory, and it will probably overflow after a few days. Is there any way to debug memory leaks in Perl? Attaching to a program and getting numbers of objects of various types would be a...
When you create an instance of the cachefactory and then don’t use it anymore the memory that was used during the creation of the object is not released. This will have a substantial effect on all web apps or scenarios where a cachfactory might be created multiple times. The symptoms of this will be unusually high memory use one the pr...
In C, something like the following would be a disaster (ie, a memory leak) because you're returning a pointer to memory that you will never be able to free: NSString* foo() { return [NSString stringWithFormat:@"%i+%i=%i", 2, 2, 2+2]; } Is that in fact totally fine in Objective-C since the memory that the returned pointer points to w...
Hi, I'm triying to find leaks in my project chibi-ORM using the tool of scan-build as suggested in other threads. But when run from the terminal: /Users/mamcx/Downloads/checker-0.138/scan-build -k -V xcodebuild I get this: 009-01-13 10:33:18.296 xcodebuild[14025:4213] Warning: Couldn't discover the 'ccc-analyzer' compiler's built-...
I'm just starting on the road the learning C, and ran into some difficulty: The code listed below is giving me the following error: Attaching to program: `/workfolder/cocoa/c_stuff/bookshelf/build/Debug/bookshelf', process 1674. Cannot access memory at address 0xa0df194 Cannot access memory at address 0xa0df194 // code start #define ...
This article http://blogs.msdn.com/tess/archive/2006/02/15/532804.aspx by Tess Ferrandez outlines why using XMLSerialization can cause memory leaks. The leak is a result of how the objects are instantiated in memory as assemblies, not objects so are not targeted by the Garbage Collector. The article was originally written on the 1.0/1....
I browse to a web page that has a javascript memory leak. If I refresh the page multiple times, it will eventually use up a significant amount of memory, and javascript on the page will slow down. On this particular page, I notice a very significant slow down when IE gets up to 100MB of RAM, even though I have multiple GB free. My ques...
Hi, we need a tool to detect easily memory leaks in an ASP.NET Application. We have an application, which consumes lot of memory. Thanks ...
