Process returned 1073741819 0xc0000005 что значит

Apparently, 0xC0000005 is the code for an access violation. Look at this guy’s question: http://tech.groups.yahoo.com/group/OpenCV/message/59196

Is there possibly a way to get around this? Recursion has never let me down before, and I found it extremely weird that it just all of a sudden did. Granted, I think 354 recursive calls is a tremendous amount, nonetheless, but I don’t understand how else to go about this problem.

Everything works just fine. However, somewhere around the 50,000th time that the program calls cvGet2D() the program exits with the message «Process returned -1073741819 (0xC0000005)».

I’d love to be able to get 50,000 recursion, but I come no where close, and I’m not even using objects. I don’t believe this is causing memory leaks, but I have no clue, I’ve never encountered something like this before.

Are you only allowed to have recursion so deep?

I’m not sure if that is your problem here or not, but yes you can only go so deep in recursion before your stack overflows.

When a function is called, stuff is put on the stack, and only unloaded when the function returns. With recursion a function keeps calling itself without returning, and things keep piling onto the stack.

Because parameters and local variables essentially belong to a function, we really only need to consider what happens on the stack when we call a function. Here is the sequence of steps that takes place when a function is called:

The address of the instruction beyond the function call is pushed onto the stack. This is how the CPU remembers where to go after the function returns.
Room is made on the stack for the function’s return type. This is just a placeholder for now.
The CPU jumps to the function’s code.
The current top of the stack is held in a special pointer called the stack frame. Everything added to the stack after this point is considered “local” to the function.
All function arguments are placed on the stack.
The instructions inside of the function begin executing.
Local variables are pushed onto the stack as they are defined.
When the function terminates, the following steps happen:

The function’s return value is copied into the placeholder that was put on the stack for this purpose.
Everything after the stack frame pointer is popped off. This destroys all local variables and arguments.
The return value is popped off the stack and is assigned as the value of the function. If the value of the function isn’t assigned to anything, no assignment takes place, and the value is lost.
The address of the next instruction to execute is popped off the stack, and the CPU resumes execution at that instruction.

In the lesson on the stack and the heap, you learned that every function call causes data to be placed on the call stack. Because the CountDown() function never returns (it just calls CountDown() again), this information is never being popped off the stack! Consequently, at some point, the computer will run out of stack memory, stack overflow will result, and the program will crash or terminate. On the authors machine, this program counted down to -11732 before terminating!

what is actually 1073741819 ? ( in Process returned -1073741819 (0xC0000005) )

I am new at coding. I code c++ in codeblocks . I don’t understand what actually 1073741819 is? Is this a range of memory or something else. Please Help..

0xC0000005 is the error code for an Access Violation exception. Windows throws that exception when code tries to access invalid memory.

So, the error message "Process returned -1073741819 (0xC0000005)" means an Access Violation exception occured in the context of the program’s main thread and was not caught by the program’s code, thus causing the program’s main() / WinMain() entry point to exit prematurely, terminating the process.

Процесс вернул -1073741819 (0xC0000005) проблему при вставке значения

Я пытаюсь создать дерево AVL и вставить в него узел. Всякий раз, когда я пытаюсь добавить значение данных в узел дерева, моя программа аварийно завершает работу и возвращает значение 0xC0000005. Вот как я ввел элемент данных в заголовочный файл:

Всякий раз, когда я пытаюсь запустить следующие строки кода в функции вставки, я получаю сбой.

Я не знаю, что я делаю не так, пожалуйста, помогите мне.

Решение

Значит код возврата 0xC0000005 STATUS_ACCESS_VIOLATION , (Вы можете найти этот и другие коды состояния NT на MSDN: NTSTATUS ценности .) Ошибка происходит из-за NULL находится вне диапазона допустимых адресов для вашей программы. Перед разыменованием переменной указателя вы должны присвоить ей адрес допустимого объекта. Например:

Другие решения

Эта строка кодовых наборов nw быть нулевым указателем, другими словами, он ни на что не указывает. Попытка разыменования нулевого указателя приведет к неопределенному поведению. Вы должны выделить память для AVLTreeNode объект, а затем получить nw указать на это.

Вместо этого вам нужно то, что выделяет память и очки nw на него:

И помните, всякий раз, когда вы выделяете память new вам нужно освободить его, когда вы закончите с этим:

Solve exit code -1073741819 (0xC0000005) error in PyCharm

When I clicked the debug button in PyCharm, this happened:

Process finished with exit code -1073741819 (0xC0000005)

Strange, it’s the first time which happens. I run it again. Nothing to do, error still comes up.

Few seconds later I was already in searching for a solution. First one suggest that it’s a Windows problem (known and now fixed apparently), so you have to add…

To Environment variables in Run/Debug Configurations dialog add this pair:

=C: as NAME and c:\» as VALUE

Did this first operation. Nothing happened.

As long as many users had this problem while using Django (but not my case), another solution you can try is this one: from PyCharm menu, go to Run – Edit Configurations – Defaults and do the next:

This should fix the error if it appears while you was using Django.

And now, my case. I tried the first solution. I tried the second (even if I don’t use Django in the project).

Let’s see the third which worked for me.

While searching for a solution, some links sent me to a PyQt forum. Even users there had this problem. Then I remembered, I installed PyQt recently. But can this be the issue ? Well, yes.

A user on Stackoverflow suggested to uncheck PyQt compatible ckeckbox in PyCharm project Settings.

So, File – Settings – Build, Execution, Deployment – Python Debugger

Remember, Settings in File menu will apply this only for the current project. If you want to solve the issue globally, select also Default Settings.

Once applied, the debugger come back to life. This worked for me after I tried the previous suggestions.
