This is a memory management question about c++ code. using namespace std; #include <iostream> #include <string.h> int main() { string a="first"; string *b= new string; *b=a; a="second"; cout << *b << ", " << a; delete b; return 0; } We can deallocate the blocks of memory that stored the string that b pointed to. I'm assuming ...
Obviously Wikipedia has a fair amount of information on the topic, but I wanted to make sure I understand. And from what I can tell it's important to understand the stack/heap relationship to really understand a memory leak? So here's what I (think) I understand. Corrections are very welcome! When you first start your program, a block ...

When I remove a TabItem from a TabControl, it still holds a reference to tab item. According to RedGate, this has something to do with EffectveValueEntry. What do I need to do to ensure the TabControl drops all references to the TabItem? ...
According to RegGate's memory profiler, my RibbonWindowis not being collected because CommandManager is holding a reference to us. Does this make sense and what can I do about it? EDIT: This appears to be specific to a RibbonWindow from Microsoft CTP. But still I would like to know why it happens. ...
Hi I think I have a memory leak in my code because every time someone connects/disconnect it doesn't free up the alloted memory so more and more memory keeps being added to the program when it isn't being used. Here's a stripped down version of the code that DOES compile; it simply accepts connections, but if you open up task manager yo...
Hi, in several example codes one can find this static NSNumberFormatter *numberFormatter = nil; if (numberFormatter == nil) { numberFormatter = [[NSNumberFormatter alloc] init]; [numberFormatter setNumberStyle:NSNumberFormatterDecimalStyle]; [numberFormatter setMaximumFractionDigits:6]; } Isn't that code producing memory ...
I release the MPMoviePlayerController but the memory allocation and the living objects are sill higher than before the object allocation. However if i reallocate the object it doesn't leak more. My application actually uses alot of media files and the memory consumption it's high. I would like to free up completely the unneeded memory to...

I have a service which creates a notification and then updates it with certain information periodically. After about 12 mins or so the phone crashes and reboots, I believe it is caused by a memory leak in the following code to do with how I am updating the notification, could someone please check/advise me if this is the case and what I ...

I'm having a memory leak problem wrapping a C++ library in PHP using SWIG. It seems to happen when callbacks from C++ containing complex types are sent to PHP while directors are enabled. Here is a standalone example to reproduce the leak: Client.hpp: #ifndef CLIENT_HPP_ #define CLIENT_HPP_ #include <vector> #include "ProcedureCallbac...
Many articles (e.g. msdn) have told be that a circular reference can not be cleaned up in some browsers when it involves a DOM object and a JS object. (IE 6 can't do it at all and IE7 can only do it between page requests): Javascript Native (Leaks): function leak(){ var elem = document.createElement("DIV"); document.body.appen...
Hey, I am trying to convert NSString to a C string using cStringUsingEncoding but I have a memory leak. My understanding is that cStringUsingEncoding returns a pointer to a character array that is only guaranteed to exist for the duration of the NSString object. As such you should copy its contents to another string. Here's where my prob...
Hi, I'm using a UISplitViewController where when the Master VC is loaded (UITableViewController) and a table cell is pressed, it creates the Detail VC (UIViewController with two UIWebViews): @implementation MasterVC - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UIViewController *de...
Hi All, I have my website written using ASP.NET. If I let it, the website will hit about 2gb physical memory used within about 3-4 days which to me sounds really bad. At the moment, I have told IIS to restart the process when it hits 500mb just to keep it under wraps but I would like to try and track down the problem. When creating a ...
I am about to conduct a workshop profiling, performance tuning, memory profiling, memory leak detection etc. of java applications using JProfiler and Eclipse Tptp. I need a set of exercises that I could offer to participants where they can: Use the tool to to profile the discover the problem: bottleneck, memory leak, suboptimal code etc...
I'm building a large RTree (spatial index) full of nodes. It needs to be able to handle many queries AND updates. Objects are continuously being created and destroyed. The basic test I'm running is to see the performance of the tree as the number of objects in the tree increases. I insert from 100-20000 uniformly size, randomly locat...
