Do You Need More RAM To Run 32-Bit Programs On 64-Bit Windows? Most computers today ship with a 64-bit version of Windows, and often a minimal amount of RAM.
This brings into question how well these systems perform. This is especially true when users want to run their legacy 32-bit software on these new computers. This is especially true when users want to run their legacy 32-bit software on these new computers. Which raises an interesting question. Do you need more or less RAM to run a 32-bit application on a 64-bit version of Windows? A Reader Asks: Is it true that running 32-bit apps on a 64-bit windows system consumes 1.5 times more memory compared to running the 32-bit app under a 32-bit Windows operating system? Bruce’s Reply: We have previously discussed benefits and drawbacks of keeping everything 64-bit across the board and some of the effects of “mixing and matching”.

Analyses d'incidents Analysez les incidents pour trouver les failles de sécurité de vos applications Adel Abouchaev and Damian Hasse and Scott Lambert and Greg Wroblewski Comment pouvez-vous vous assurer qu’une panne de programme n’est pas exploitable ?
La réponse est simple : vous devez supposer que chaque panne est exploitable et résoudre le problème ! Il s’agit là d’une question de qualité et il est souvent plus économique et plus pratique de résoudre le problème avant que le produit ne soit expédié au client. L’analyse des pannes de programmes liées à la corruption de la mémoire afin de comprendre les ramifications de sécurité peut s’avérer une tâche complexe et sujette à des erreurs. N’oubliez pas que les pannes ne se manifestent pas toutes d’une manière observable.

Why does Software Crash #1 – The Access Violation - Software Test Engineering @ Microsoft. Pop quiz: what does this line of code do when executed?
Int foo = (*((int*)0)); If you’re an astute reader, you can solve the answer just by reading the title of the blog post. But, more interestingly, let’s forget about that buzzword and analyze exactly what’s happening. The access violation is probably the most common crash in unmanaged software, so let’s break it down piece by piece to discover what’s happening. int foo; int * ip = NULL; foo = *ip; //crash! On the first line, we declare an integer variable named “foo”. The second line declares a pointer to an integer named “ip”, and initializes this value to NULL (which is simply a fancy term for 0). The third line attempts to grab the value of address 0, which is prohibited, and assign it to our variable “foo”. Unhandled exception at 0x004173c8 in cpractice.exe: 0xC0000005: Access violation reading location 0x00000000.
Debugging a Stack Overflow (Windows Debuggers) A stack overflow is an error that user-mode threads can encounter.
There are three possible causes for this error: A thread uses the entire stack reserved for it. This is often caused by infinite recursion.A thread cannot extend the stack because the page file is maxed out, and therefore no additional pages can be committed to extend the stack. A thread cannot extend the stack because the system is within the brief period used to extend the page file. When a function running on a thread allocates local variables, the variables are put on the thread's call stack. The amount of optimization is influenced by compiler settings applied at build time. The first step is see what event caused the debugger to break in: 0:002> .lastevent Last event: Exception C00000FD, second chance You can look up exception code 0xC00000FD in ntstatus.h, which can be found in the Microsoft Windows SDK and the Windows Driver Kit (WDK).
Download Desktop Heap Monitor Version 8.1 from Official Microsoft Download Center. User32.dll or Kernel32.dll fails to initialize. Sometimes an application that is executed by either CreateProcess() or CreateProcessAsUser() fails and you receive one of the following error messages: Initialization of the dynamic library <system>\system32\user32.dll failed.
The process is terminating abnormally. Initialization of the dynamic library <system>\system32\kernel32.dll failed. The process is terminating abnormally. The failed process returns the exit code 128 or Cause 1 The executed process does not have proper security access to the window station and desktop associated with the process. The lpDesktop member of the STARTUPINFO structure passed to CreateProcess() or CreateProcessAsUser() specifies which window station and desktop is associated with the executed process.
